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

What each ingredient does

Demerara sugar
Provides sweetness and caramel-like flavour as the mixture cooks down.
Granulated sugar
Adds sweetness and helps the mixture set firm as it thickens.
Syrup
Keeps the sugar smooth and adds moisture so the toffee stays tender.
Swiss milk (milkmaid brand)
Adds milk solids and sweetness for a creamy, browned toffee flavour.

The step that matters

Boil the mixture for 1 hour, stirring constantly. Constant stirring stops sugar from scorching on the base of the pot during a long boil. Scorched sugar turns bitter and dark, so keeping the mixture moving protects the flavour.
