Butter Taffy

Ingredients

Directions

Make the taffy

  1. Mix sugar, syrup, vinegar, water, and salt in a saucepan.

  2. Heat slowly, stirring until sugar is dissolved, then boil without stirring to brittle stage (290°F).

  3. When syrup is nearly at 290°F, add butter; add vanilla just before pouring out.

Set and cut

  1. Pour into a buttered pan; mark into squares when cool.

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

What each ingredient does

Yellow sugar
Forms the sweet, brittle body of the taffy as it cooks to hard crack.
Golden syrup
Inhibits sugar crystallisation, keeping the taffy smooth rather than grainy.
Butter
Adds fat for a softer, richer bite and a buttery flavour.
Vinegar
Acidity helps prevent sugar from crystallising, keeping the texture smooth.

The step that matters

Boil without stirring to brittle stage. Stirring once the syrup boils can trigger sugar crystals, making the taffy grainy. Reaching the target temperature sets the final hardness, so the cook must hit 290°F rather than stop early or overshoot.
