Why it works: Sugar and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Sugar Taffy
Ingredients
Directions
Make the taffy
Combine brown sugar, butter, and enough water to moisten the sugar in a pot.
Boil the mixture without stirring for about 45 minutes, or until it becomes crisp when dropped into cold water.
Set and break
Pour the hot mixture into pans or platters, spreading it as thin as possible.
Allow to cool before breaking into pieces.

What each ingredient does
- Brown sugar
- Provides the bulk of the sweetness and, as it cooks, the caramel flavor and hard structure.
- Butter
- Adds fat for a rich flavor and a smoother, less brittle bite.
The step that matters
Boiling without stirring. As the sugar syrup heats, its concentration rises and it hardens when cooled. Stirring can cause sugar crystals to form, making the taffy grainy instead of smooth. Judging doneness by the cold-water crisp test matters because undercooked syrup stays sticky and overcooked syrup becomes brittle.
