Name: Chewing Taffy
Ingredients: 4 pounds granulated sugar; 2 pounds glucose; ¼ pound butter; ¼ pound nucoa butter; 1 ounce gelatin; sweet cream (enough to dissolve sugar); vanilla (for flavoring); ½ pound bitter chocolate (optional, for chocolate flavor)

Why it works: Vanilla and chocolate are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Chewing Taffy

Ingredients

Directions

Make the taffy base

Combine granulated sugar, glucose, butter, nucoa butter, and gelatin dissolved in hot water in a kettle.
Add enough sweet cream to dissolve the sugar.
Cook the mixture to about 260°F (127°C).

Cool, pull and flavor

Pour the cooked mixture onto a slab and let it cool.
Once cool, pull the taffy on a hook and flavor with vanilla.
For chocolate flavor, add ½ pound of bitter chocolate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Granulated sugar: Provides the sweet body and, when cooked, the firm structure of the taffy.
Glucose: Inhibits sugar crystallization, keeping the taffy smooth and chewy rather than grainy.
Butter: Adds fat for a softer bite and rich flavor.
Gelatin: Adds elasticity so the cooked mass can be pulled and holds its chewy texture.

The step that matters

Cook the mixture to about 260°F (127°C). The final temperature sets how firm the taffy will be once cool. Undercooking leaves it soft and sticky, while overcooking makes it hard. Sugar concentration rises as water boils off, so the reading determines texture.
