Christmas Taffy

Ingredients

Directions

Make the taffy

  1. Melt the brown sugar and butter together in a saucepan over medium heat.

  2. Stir continuously until the mixture reaches the hard ball stage (it will break when dropped in cold water).

  3. Remove from heat and add the extract for flavor.

Set and cut

  1. Pour the mixture into buttered plates.

  2. Before it hardens completely, score the taffy into squares.

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

What each ingredient does

Brown sugar
Provides the bulk of the candy and its caramel sweetness and flavor.
Butter
Adds fat that keeps the taffy tender and smooth rather than grainy.

The step that matters

Stir continuously until the hard ball stage. Sugar syrup must reach the correct temperature to set firm but chewy. Stopping early leaves it soft and sticky, while cooking too long makes it brittle. Constant stirring keeps the sugar from crystallizing or scorching on the pan bottom.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, butter):

  1. Vanillafits better
  2. Figfits better
  3. Peachfits better
  4. Lemonthe original

Fit is the average pairing score against sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
