Beer and Candy, yet again

One of the surprises in my candy research has been the intimate and unexpected connections with liquor. Brandy drops and the like barely scratch the surface. Take, for example, the case of invertase.

Invertase is one of the candy chemist’s little secrets. It is an enzyme that splits sucrose (table sugar) into smaller pieces: glucose and fructose. You can buy invertase from kitchen chemical supply companies. It is used to make fondant smoother. And most important, invertase is the magic ingredient that makes possible dipped chocolates with liquid centers. Confectioners start with a solid, fondant center made with invertase; after the solid center has cooled, the invertase goes to work and within a few days, the fondant has turned to liquid.

Invertase sounds like a scary chemical additive, but actually it is active in all kinds of natural processes. It is what helps bees transform nectar into honey. And each of us carries around our own personal supply, right in our own mouths as part of the chemistry of saliva.

Invertase was first discovered by nineteenth century chemists who were studying the effect of yeast on sugar. They noticed that the sugar changed form before it started fermenting, and eventually they isolated the enzyme that caused this effect. By 1900, processes for deriving invertase from yeast were well known, and over the next decades chemists would develop many uses for invertase derived from yeast, most importantly in candy-making.

And where did that yeast come from? Some of it may have come from factories like Fleischmann’s that were manufacturing yeast for home and commercial baking. But some of it came from breweries.

Yeast is a by-product of the beer brewing process; when the beer is done, the yeast settles at the bottom of the tank. Storage and re-use is possible, but there are some difficulties. Instead of throwing it away, some brewers’ ended up donating or selling the waste to be turned into invertase.

One chemist, by the name of Sidney Born, was able to complete his 1913 dissertation on the chemical constitution of invertase thanks to the generosity of the Jacob Ruppert Brewery, who furnished Born with 200-pound barrels of compressed yeast from time to time. Born describes a complicated and tedious process lasting several weeks; eventually, 200 pounds of yeast would yield 200 grams of invertase.

Based on Born’s process, I calculate almost a pound-for-pound transformation from yeast to finished candy product. Candy makers using invertase undoubtedly accounted for a huge quantity of brewery waste after Prohibition ended.

So there you have it: from beer to candy, via the chemistry lab, and a nice story about industrial recycling as well.

Panning for Sugar Plums

I have been investigating the term sugar plum, which refers to a panned seed or nut candy (comfit or dragee) from the seventeenth to nineteenth centuries. Think a small jaw breaker, but with a caraway seed at the center. Sugar plum could also refer in the nineteenth century to confectionery in general, or more narrowly to the sorts of candy that are smaller and rounder. My essay on sugar plum should be appearing on The Atlantic web site shortly, but meanwhile here I wanted to share some interesting descriptions of candy manufacture that I came across in my research.

An 1868 magazine article on “Sweets and their Manufacture” introduces readers to the innovations in confectionery made possible as a result of steam heat. Here is a detailed description of the process that yields the sugar plum, in this case based on an almond:

The veritable sugar-plum, or almond-drop, is made in a very interesting manner. A number of almonds, after being coated with a little gum to catch the white sugar, are thrown into a deep pan surrounded with steam. This pan revolves sideways at an angle of forty-five degrees. As it revolves the almonds, of course, tumble over one another, and whilst they are doing so, the workman pours over them from time to time liquid white sugar, allowing a sufficient time to elapse between each supply for the sugar to harden upon the comfit. In this way it grows by the imposition of layer upon layer, until it is the proper size. By this simple motion, the sugar is deposited in the smoothest and most regular manner.

This is a description of the process confectioners call “panning,” and the finished product will be familiar to modern readers as a species of what we call “Jordan almonds.”  A similar process is the basis for the broad category of comfits.

Even with the aid of a mechanized rotating pan and steam heat, comfits are a tedious and exacting enterprise. And when it was done by hand, comfit making took days. Although the author of this 1838 recipe insists that comfits may be “easily made at home,” the extensive instructions belie this easy reassurance:

A preserving-pan must be provided with two handles, through which a string is fastened that runs across, which is connected with a pulley attached to a beam, so that at the least touch, the pan rises or falls, or swings backward and forward. … There must be, besides this pan, two saucepans, one to hold a slightly warm solution of gum arabic, the other to contain some syrup which is boiled during a quarter of an hour, when some of finest white starch of wheat is dissolved in water and mixed with it. Under the swinging-pan there is a charcoal fire at a sufficient distance to give it only a gentle heat. The seeds of which the comfits or sugar-plums are to be made, are put into the swinging-pan when it is just warm. A ladleful of the solution of gum is poured over them, and the seeds are briskly stirred and rubbed with the hands till they feel dry; a ladleful of the syrup mixed with starch is next poured in, and the seeds again rubbed and stirred till they are dry. This process is repeated until the comfits have undergone the first operation. They are then set in a stove to dry. Next day the operation is repeated, the quantity of starch being varied and the syrup made stronger; and so on every day till the comfits are of the requisite size.

… Good sugar-plums take five or six days in making. … Comfits are made with caraway seeds, cardamums, bleached almonds, and a variety of other things.

According to Laura Mason in The Prehistory of Sweets, prior to the invention of labor saving machinery the techniques for making comfits were closely guarded and few had the expertise to make them. So comfits or sugar plums were a luxury good, most likely to be found in an aristocrats pocket or between courses at a very decadent royal banquet. Isn’t it nice to think that jelly beans and M&Ms, our contemporary version of panned candies, have such a noble ancestry?

Candy Machine Revolution

If you think candy is all about sugar and chocolate, you’re wrong.

Candy is all about the machines.

Sure, without machines you can make a bit of candy. And if we just ate a few pieces of fudge at Christmas and a bite of taffy once in a while, that might be fine. But America is a great candy eating nation! And to make the huge quantities of cheap candy that will put mounds of sweets in every store on every corner on every day of the year, you need machines. Machines for mixing and cooking and pouring and molding and cutting and wrapping revolutionized candy. Over a few decades at the end of the nineteenth century, American confectionery was transformed from a small, local craft into a huge industry.

Today we take the machines for granted. In the beginning, though, there was wonder and amazement at what a machine could do. Here is a glimmer from the very beginning, as described in a 1864 book on the “art of sugar boiling”:

Twenty years since [c 1840] it was considered rather a clever thing (with a pair of scissors, the principal tool a sugar boiler used) to cut a seven pound boil of acid drops to size, and with the help of a practised boy, make them round and press them flat, with the hands, in half-an-hour. The same quantity may now, with the machine, be made into drops, by the boy alone, in five minutes.

The machine meant that the same boy could be six times as productive. And the skill of working the machine was far less specialized than the craft of working hot sugar. Labor costs go down, productivity goes up, cheap candy zooms out of the factory and into the belly of the nation.

Vegetable Candy Revolution

I finally got my hands on the 1912 candy cookbook classic, Candy-making Revolutionized. Until now, I’ve only known this book by reputation, and it was the reputation of a total crack-pot. The “revolution” that author Mary Elizabeth Hall promises is this: candy from vegetables.

When I first heard about this book, I made snarky comments about the preposterousness of potato creams and lima bean taffies. I assumed Hall was another of those “food faddists,” prophets of health who promoted wacky ideas like chewing your food one hundred times or eating only uncooked foods.

After all, we know that “vegetable” and “candy” are at the opposite ends of the food spectrum. Vegetables are good for you. Real food. Eat your vegetables. And candy? Barely food. Certainly, of all the things you can eat, the one that is the very worst. So I assumed that Hall’s proposal to make candy that is really vegetables was another of those food tricks: disguise and dishonesty, sneaking in the virtue under the mask of artificial vice.

I was wrong. Hall is not trying to sneak or disguise anything. Hall doesn’t have an axe to grind, and she has nothing at all against candy. She just thinks that making candy with vegetables is a good idea. And now that I’ve read the book, I have to admit to a certain admiration for Hall and her project.

The vegetable candy future Hall envisions is “purer, more wholesome, more nourishing” than that of the past, to be sure. But there is much more to recommend it.

Half the book is dedicated to decorative and artistic candy forms made with potato-based confection. She gives recipes for a sort of potato-sugar modeling dough. This substitutes for marzipan at a substantially lower cost. The potato can be shaped, molded, colored, painted, and eaten. Hall proposes this craft as a home-based business with in the reach of even the most rustic hausfrau. Every village that can muster up a ration of potatoes and sugar will be showered with potato candy roses and potato candy violets. In schools where home economics and fine arts are taught to young ladies, potato confectionery promises the most ingenious combination of the two disciplines: every girl will learn the principles of line and color while turning out edible potato castles and gnomes.

Beyond this decorative use, Hall presents vegetables in candy as having their own distinctive merits. There are colors like the red of beets and the orange or yellow of carrots that are vivid and lovely. There are new flavors from novel ingredients like green beans and rhubarb.

But the best thing about vegetable candy, at least to Mary Elizabeth Hall’s way of looking at things, was the way it solved the problem of appetite. Hall didn’t see anything wrong with candy, nor with the craving for candy. Quite the contrary: Hall thought of candy as a good form of energy food, and saw the craving for sweets as natural and benign. But children didn’t always know when to stop, and that might make them sick to their little tummies. Vegetable candy solves the problem:

Sugar it of course contains, but the vegetable base supplies no small part of the bulk; consequently children may eat their fill of it and satisfy their natural longing for candy without having gorged themselves with sugar.

It is worth noting here that the virtue of the vegetables in the candy is not the vegetables themselves, but their physical property of “bulking.” Americans were not, in 1912, all that interested in vegetables. No one had ever heard of vitamins, and the nutrition science of the day focused teaching people to view their food “scientifically” as so many calories or so much protein or carbohydrate.

Today, we have a totally different perspective on vegetables. Candy itself is trending “healthy.” So I’m wondering how long it will be before some 21st century entrepreneur discovers these recipes?

Candied carrot-rings, candied parsnips, and sweet potato patties incorporating coconut and nuts all would find, I suspect, an eager market in the artisanal food stalls popping up in every major city these days.  And the recipe for tomato marshmallow sounds brilliant. Think tomato as fruit, think the color and a little subtle flavor. Candy making techniques have not changed in the last hundred years, anybody could follow these recipes. Any takers?

The recipes are here. The time is right. Mary Elizabeth Hall was just a century before her time.

“Decayed Rocks Used in Candy”

As reported in the Philadelphia North American on November 30, 1908:

Grubbstown, Pennsylvania,  Nov 29. The astounding discovery has been made here that impure and decayed rocks are being used in the manufacture of rock candy.

How long this violation of the law has been going on is not accurately known, but certainly the fraud is widespread and thousands of persons have been cheated, if not positively harmed, by the men who have been carrying on their wicked work.

Special Agent Horatio Acornley, who has been investigating the matter for several weeks, says he can produce positive proof that several large candy manufacturers have been buying rotten rock at a low price and using it most exclusively in making rock candy.

“Thosands of innocent children have thus been exposed to the poison,” said Mr. Acornley, “and I would not be surprised to learn that it is responsible for many cases of hardening of the heart which have been reported to us.”

“As every one knows, only the best quality of rocks should be used…and we propose to bring suits against the guilty wretches.”

“In this connection I may say that I am looking into several cases of using poor limestone in making lime drops.”

Candy Professor adds:

It was these sorts of stories that made V.L. Price, the Chairman of the N.C.A. Executive Committee in the early 1900s, positively crazy. He was charged with responding to press accounts of poisoned or adulterated candy. So when the North American published this satirical piece, he put pen to paper to patiently respond, no, there is no rock in “rock candy,” only good pure sugar, and of course there are no limestones in lime drops either.

Which pedantry seems excessive, were it not for the fact that some time later Price found the Minneapolis Tribune publishing an investigative report  raising the alarm about the use of crushed rocks in rock candy and limestone in lime drops.  Price remarked wryly:

Of course, in gay Philadelphia they all saw the joke as it appeared in the paper’s columns as a fake, but in staid old Minneapolis they all took it seriously.

Or at least Marion Harland, the author of the Minneapolis piece, took it seriously. Just goes to show, you can’t believe everything you read in the papers!

All About Licorice

close-up of rolls of liquorices

First off, Twizzlers aren’t really licorice. In fact, many of the candy we think of as “licorice flavor” is in fact flavored with anise. But real licorice, from the root of the licorice plant, is quite amazing stuff. In a recent post, I described the multitudes of licorice candies that were popular in the early 1900s. And licorice itself played an important part in many American industries in the first half of the twentieth century.

A little science: glycyrrhizin is the name of the sweet substance in licorice root. This chemical, found in significant levels only in the root of the licorice plant, is fifty times as sweet as sugar. That’s a lot of sweet!

But the virtues of licorice are not just in the sweetness. Licorice root is a favorite with herbalists today, and boasts a medicinal history going back thousands of years. Licorice root has been used for eons as a health tonic, as a blood purifier, as a means of relief from sore throat and internal inflammations. And it isn’t just good for your insides. Mixed with honey, licorice has been used as a healer of sores and wounds.

Don’t think it’s just the health-foody types who believe in the healing power of licorice. Modern medical researchers are documenting its effects on the body. Did you know licorice (the real stuff) can raise your blood pressure? Of course, you should consult your doctor if you have questions about the medical effects of licorice. But you can safely consult Candy Professor for information about the history of uses of licorice in confectionery and elsewhere.

By the 1930s, U.S. industry was importing some 35,000 tons of licorice root per year, for use in a wide variety of industries. Attempts to grow licorice domestically were unsuccessful, so most licorice root was imported from Spain and Italy where it was cultivated commercially.

The first step in processing the licorice was to shred the roots. Then a process of grinding and sifting and grinding would yield the first product: powdered licorice root, to be used in pharmaceutical prepartions. The coarse remainder would be bathed in a solution, which produced a liquid extract. This second extraction would be reduced to a syrup or paste to form the base needed for candy making, and also for flavoring tobacco.

But they weren’t finished yet. After candy, cigars, and drugs had taken what they needed, the brewers had a turn. Yes, in the olden days, beer makers would add licorice to their brew to give it a foamy head. And the foaming properties of licorice extract suggested yet another use: fire extinguishers. Licorice extinguishers, which formed an oxygen-free foam, became important in fighting oil fires in the days before chemical extinguishers.

At last, there was nothing left of the licorice root but stringy fibers. These were not wasted either. The fiber was dried and made into insulating wall and box board. So the box your licorice candy was packaged in might also be made of licorice!

Potato Caramels and Parsnip Nougat

I’m starting to realize that you can make candy out of anything. Rocks, even. Oh, wait, that “rock candy” isn’t really made of rocks… (or is it? see this post for more on the question of rocks in rock candy).

But anything edible, you can bet somebody somewhere tried to make a candy out of it. In fact, in some countries what I might consider “peculiar” for a candy ingredient is quite ordinary. Take Mexican Dulces de Calabasas, for example. Squash candy. I wouldn’t have come up with that. Or an Asian favorite, Durian taffy. That’s made of the fruit that smells, to the un-initiated nose, like a diaper pail. You see how provincial I am when it comes to candy flavors.

But luckily, many others have ventured boldly. Our global village is bringing us all sorts of interesting flavors. And a look to the past shows that even here in America, more intrepid candy inventors have imaginations wider than the produce aisle.

I’m thinking of Mrs. Ellen Gillon, of Honesdale, Pennsylvania. This was a while back, of course, 1911 to be precise. Mrs. Gillon’s husband had died, and she was left to fend for herself. She explained:

One day, when I was thinking of schemes to make money, the idea of vegetable candy occurred to me. I experimented for several weeks before I hit upon the process, and as far as I know, I am the only one in the world who knows it

Mrs. Gillon wouldn’t say how she made the candy, only what it was made of: the finest vegetables she could gather from the garden. At Mrs. Gillon’s shop, you could sample potato caramels, parsnip nougat, turnip fudge, beet marshmallows, and bean taffy.

Mrs. Gillon herself claimed to live “almost entirely on vegetables” and to eat little candy. Once her vegetable confections were perfected, though, she could one supposes, live almost entirely on candy vegetables! Not to mention all the children of the neighborhood, for whom “eat your vegetables” would sound entirely delectable.

    Tough Tootsie, and How It Got To Be That Way

    Durable. Rugged. Stands the test of time. That’s what you expect from radial tires. Not so much from candy.

    But that’s the Tootsie Roll. Built to last. Tootsie Roll Industries describes the candy’s peculiar durability as “its non-perishable quality and resistance to extreme weather conditions.” I’ll say. It’s pretty amazing that a candy renowned for surviving under war conditions should end up near the top of America’s favorite treats.

    How, you might wonder, did the Tootsie Roll get to be that way? Because if it weren’t for that non-perishable resistance, Tootsie Roll would have been just like any other chewy American candy of the early 1900s.

    The secret is in the patent. U.S. Patent number 903,088, awarded to Leo Hirschfeld on November 3, 1908 with the unassuming name “A process for making candy.”

    Normally a candy like taffy would be made by boiling the sugar mixture to a certain temperature, then pulling it on forks as it cooled, which would incorporate tiny air bubbles,  making it lighter in color and creating that chewy texture. Once it had cooled, you could cut it into pieces and wrap it.

    What Leo figured out was that if you baked the candy at a low heat for a couple of hours after you pulled it but before you shaped it, the texture would be transformed from regular sticky taffy to the particular and peculiar texture of Tootsie Roll. The second cooking would cause the candy to rise like a cake, and become more light and porous. And it would make the candy a little tough, Leo admitted: “while tough in a measure it is not unpleasantly so, and will after a reasonable length of time thoroughly dissolve in the mouth.” That sounds about right.

    Beecause Hirschfeld patented this process, no one else could do it. The patent was a very big deal in 1909. Tootsie manufacturer Stern & Saalberg Co. made sure everybody knew they had sole legal right to the Tootsie Roll process, and that they would prosecute anyone who tried to steal it. If you didn’t know, you could read it plainly at the bottom of their first known ad (shown here), which appeared in Confectioners Journal in May 1909:

    The process for making Chocolate Tootsie Rolls is Patented. We have $50,000 laid aside to protect our rights.

    The name “Tootsie” was also a registered trade-mark, protected by U.S. Patent and Trademark law. And in case you forgot, the patent was right there on the label of every single Tootsie Roll. The print is a little fuzzy, but it says “Tootsie Reg. U.S. Pat. Office” all over the label.

    Detail of wrapper from early Tootsie Roll ads (1909-1912)

    There is no candy like a Tootsie Roll, then or now. Pretty smart, that Leo Hirschfeld.

    Some Candies You Won’t Be Making for the Holidays

    close-up of a bowl of assorted candy

    This time of year, some people fire up the stove to make home made candies. Maybe some walnut fudge? or how about candied orange peels?

    We’re accustomed to the typical fruits and nuts that flavor our candy. But over the past century, some intrepid inventors have pushed the boundaries of “candy flavor” to experiment with new and strange candies:

    Horseradish Bonbons: A recipe published in 1915 suggested boiling horseradish in sugar syrup, and using this as a base for a chewy candy treat. You can enjoy it as a snack, or as a side dish with your Roast Beef.

    Candy from Cottonseed: The Saint Louis Cotton Oil Company found itself with a lot extra cottonseed on its hands in 1915. Why not cottonseed candy? They produced caramels and a chewy taffy-like candy. The project never took off, as the market value of the oil was too high to make the candy a practical proposition. But tasters found it agreeable, and said if they didn’t know what it was, they would have taken it for a good brand of molasses candy.

    Alfalfa Candy: In 1915, a man in Montana claimed he could make 75 varieties of candy from alfalfa. This would be, I suppose, the sort of candy you would offer your horse or your hamster.

    Lima Bean Taffy: How to get the kiddies to eat more vegetables? Hide them in the candy! A century before Jessica Seinfeld and the Sneaky Chef, Mary Elizabeth Hall came up with a whole cookbook of “alternative” vegetable candies. Vegetable candy seemed a great solution for intemperate candy lovers: it “furnishes the valuable element of sugar so combined with nutritious vegetable bases that, because of the bulk, there is no temptation to overeat!” Or, perhaps, because of the taste… (Candy-Making Revolutionized, 1912)

    Alayam: This was an experimental candy made from sweet potatoes. The mid-century story of Alayam is an interesting case of what happens when agricultural policy meets the candy dish. Another “not quite ready for prime time” experiment, you can read more about it in the post about Alayam.

    Candy Making in Brooklyn, 1908

    I happen to live in Brooklyn, so it is with pride that I relate Brooklyn’s glorious candy days past. In 1908, Brooklyn ranked among the top confectionery manufacturing cities. Brooklyn alone accounted for 130,000,000 pounds of confectionery and chocolate a year, at a value of some $10,000,000. The population of the borough in that year was 1,640,400; so that’s almost 80 pounds for each man, woman, and child. The biggest candy factory in the world was on Lorimer Street, churning out 36,000,000 pounds of confection a year for the candy starved masses. All that candy didn’t stay in Brooklyn, though. Brooklyn candy makers exported more candy than those of any other city, and Brooklyn-made candies could be found in every state of the union.

    Brooklyn was a great place to be a candy eater, too. In 1908, there were some 560 shops dedicated to the sale of candy, and many of those shops were also making their own candies on site. Plus, you could buy candy at drug stores, news stands, stationers, department stores… well, the fact is, it would have been hard to not buy various, interesting, fresh, locally made candy in 1908, if you found yourself on the streets of Brooklyn.

    One candy seller described his typical male customer’s candy-eating habits:

    [Men] are at it all the time–and eat much more at a time than they used to.It is the men who keep the candy business going. Where they used to buy a box once in a while and carry it home, now they come into a store like this and buy 5 or 10 or 15 cents worth just for themselves and eat it right up.

    5 cents in 1908 would buy you a good-sized bar, or a pouch of smaller candies, about what a dollar buys today. 15 cents worth of candy would have been a hefty amount to “eat right up”!

    No wonder America was known in that day as a nation of candy eaters. Brooklyn’s 560 candy shops served 1.6 million people. Today, we have 250 listings in the Yellow Pages under “candy,” and the borough population is closer to 2.5 million. Most candy comes from drug store and grocery racks, the same familiar Hershey and Mars and the like. Yeah, we still eat candy, but not like in those good old days…
