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

What each ingredient does

White sugar
Provides sweetness and, as it cooks, the firm, brittle structure of the toffee.
Butter
Adds fat for a rich texture and a smooth, glossy mouthfeel.
Milk
Adds moisture and creaminess, and its milk solids help give toffee its colour and flavour.
Chocolate
Contributes cocoa flavour and a deeper brown colour to the toffee.

The step that matters

Simmer slowly and stir constantly. Sugar and milk solids can scorch on the base of the pan over direct heat. Constant stirring spreads the heat evenly and keeps the mixture from burning, while cooking until it pulls away from the sides concentrates the sugar so the toffee sets firm rather than sticky.
