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 and enough water to moisten it in a large pot.
Add butter and bring to a boil.
Boil without stirring for about 45 minutes, or until a small amount dropped into cold water forms a crisp ball.
Set and break
Pour the mixture into pans or onto 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 candy and its sweet, molasses-rich flavor.
- Butter
- Adds fat for a smoother, richer texture and a softer bite in the finished taffy.
The step that matters
Boil without stirring until a crisp ball forms in cold water. Stirring can trigger sugar crystallization, leaving the taffy grainy. Sugar reaches the hard-crack stage as water evaporates and concentration rises, so the cold-water test indicates when it is done. Undercooking leaves it sticky; overcooking makes it brittle.
