Science of Cooking: Taffy Recipe: What’s Going On? (1)

What’s Going On?

• Why do I add cornstarch?
The addition of cornstarch (called cornflour in British recipes) helps give the taffy a smooth texture.

• Why do I add corn syrup?
Corn syrup acts as an "interfering agent" in this and many other candy recipes. It contains long chains of glucose molecules that tend to keep the sucrose molecules in the taffy syrup from crystallizing.

In this taffy recipe, the butter also acts as an "interfering agent"—the milk proteins in the butter interfere with crystal formation as well.

• What is glycerin?
Glycerin is a sweet, slippery, colorless liquid that's made from fats and oils and is most often a by-product of the soapmaking process. It's used in many soaps and cosmetic products, cake icing, as a lubricant, and to make nitroglycerin—an ingredient in dynamite! (Note: glycerin itself is not an explosive substance, so it’s safe to use in your kitchen!) In this taffy recipe, glycerin helps give the candy a soft, creamy consistency.

Glycerin can be found in many drugstores, as well as some supermarkets and craft stores in the baking supplies section, or in cake-decorating stores. Be sure to purchase food-grade glycerin.

• Why do I need to stop stirring after the syrup begins to boil?
At this point, you have dissolved the crystal structure of the sugar. Stirring or other agitation is one of the many factors that can encourage the fructose and glucose molecules in your syrup to rejoin and form sucrose—crystals of table sugar.

• Why do I wash down the sides of the pan?
The sugar crystals are dissolved at this point in the process. But a single seed crystal of sugar clinging to the side of the pan might fall in and encourage recrystallization.

• Why do I need to pull the taffy?
Pulling taffy aerates it, or incorporates many tiny air bubbles throughout the candy. This makes it lighter and chewier.

FAQs

What is the science behind making taffy? ›

The stretching and folding aerates and emulsifies the candy, incorporating small air bubbles and breaking down larger oil droplets. "Taffy is composed of oil droplets and air bubbles of various sizes dispersed in a viscoelastic matrix (sugar syrup)," Chan said.

What does glycerin do for taffy? ›

In this taffy recipe, glycerin helps give the candy a soft, creamy consistency. Glycerin can be found in many drugstores, as well as some supermarkets and craft stores in the baking supplies section, or in cake-decorating stores.

What is the composition of taffy? ›

The basic recipe for taffy calls for sugar and molasses or corn syrup to be heated with water to a prescribed temperature.

What country invented taffy? ›

Taffy is a type of candy invented in the United States, made by stretching and/or pulling a sticky mass of a soft candy base, made of boiled sugar, butter, vegetable oil, flavorings, and colorings, until it becomes aerated (tiny air bubbles produced), resulting in a light, fluffy and chewy candy.

What is the difference between taffy and salt water taffy? ›

Regular Taffy. Since salt water taffy gained its moniker following that offhanded comment after the flooding in Atlantic City, there is really no difference between salt water taffy and regular taffy. There was little or no salt added to the candy over 100 years ago or now.

What makes taffy chewy? ›

Like all soft taffy, saltwater taffy is made by stretching or pulling a mixture of sugar and fat over and over until it becomes aerated, or filled with small air bubbles. This gives the mixture a soft, chewy texture that can then be molded into bite-sized pieces.

What makes taffy hard? ›

We cook each batch according to the temperature of the day. If it's very cold outside, the candy is cooked at a lower temperature, which produces a softer candy. The opposite holds true when the temperature is above 70 degrees Fahrenheit. We cook the taffy to a higher degree, producing a slightly firmer piece of candy.

Why does taffy turn white? ›

The purpose of pulling the taffy is to add air in to the candy. This allows for millions of air bubbles to form which is how a clear batch of cooked taffy all of a sudden begins to turn bright white. The added air into the product also adds volume, and turns the candy into a much larger piece.

Are Tootsie rolls taffy? ›

What gives taffy an elastic texture? ›

“In some sense, oil droplets and air bubbles are like rubber balls. When deformed in the taffy, they tend to return to their original, spherical shape because of surface tension. In other words, emulsification and aeration make taffy more elastic, hence, chewier.”

How do you firm up taffy? ›

Taffy is just as sensitive to cold as it is hot, meaning that melted taffy is easily rejuvenated to its regular consistency. The best solution to melted taffy is merely to let it set unbothered at room temperature (72 for a period of 24 hours.
