Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides liquid and dairy richness that softens the chewy texture of the taffy.
- Chocolate
- Adds chocolate flavour and some fat, colouring the taffy dark.
- Sugar
- Provides sweetness and, once boiled, the firm sugar structure that sets the taffy.
- Molasses
- Adds deep flavour and moisture, and darkens the taffy.
- Butter
- Adds fat that gives a smoother, less brittle chew.
- Baking soda
- Reacts with the acidic molasses to lighten the mixture and soften its texture.
The step that matters
Boiling for about an hour. The mixture must be boiled constantly so enough water evaporates and the sugar concentrates; too little boiling leaves a soft, sticky taffy, while overcooking makes it hard and brittle.
