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

What each ingredient does

Granulated sugar
Provides the sweet, crystalline base that sets firm as the syrup cooks down.
Grated chocolate
Supplies the chocolate flavour and adds body to the syrup.
Butter
Adds fat for a softer, richer bite in the finished taffy.

The step that matters

Continue boiling until the candy snaps. Sugar syrup sets harder as its water evaporates and its temperature rises. Stopping too early leaves a sticky, soft taffy, while boiling too long makes it brittle and hard to pull.
