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

What each ingredient does

Sugar
Melts and hardens as it cools, forming the brittle candy structure and sweetness.
Peanuts
Add crunch and nutty flavour that contrasts with the hard, glassy sugar.

The step that matters

Stirring constantly while the sugar melts. Sugar can scorch or crystallise on the bottom of the pan if it is left unstirred over heat. Constant stirring helps it melt evenly, so the candy cooks to a clear, uniform base.

Swap the peanut

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

  1. Almondfits better
  2. Pecansfits better
  3. Filbertfits better
