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 ↓
Sugae Toffee
Ingredients
Directions
In a large pot, combine the brown sugar and enough water to moisten it.
Boil the mixture without stirring until it reaches a crisp stage when dropped into cold water, about 45 minutes.
Pour the hot toffee into pans or onto platters, spreading it as thin as possible.

What each ingredient does
- Brown sugar
- Provides the main sweetness and, as it cooks to a crisp stage, forms the hard brittle structure of the toffee.
- Butter
- Adds richness and fat, giving the toffee a smooth texture and a buttery flavour.
The step that matters
Boiling without stirring. Stirring can trigger sugar crystallisation, making the toffee grainy instead of smooth. Sugar must reach the crisp stage in cold water to set hard, so undercooking leaves it sticky and overcooking makes it bitter.
