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

What each ingredient does

Light brown sugar
Forms the syrup that sets into a crisp, sweet, airy candy structure.
Egg white
Traps air when beaten, giving the candy its light, foamy texture.
Chopped walnuts
Add crunch and nutty flavour that contrast with the airy candy.

The step that matters

Boil the sugar and water until it threads. The syrup's sugar concentration decides the final texture. Stopping too early leaves a soft, sticky candy that may not set, while cooking too long makes it hard and brittle.

Swap the walnut

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

  1. Pecansfits better
  2. Almondfits better
  3. Chestnutfits about as well
  4. Walnutthe original

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