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

What each ingredient does

Sugar
Forms the syrup base that sets into the crisp, sweet candy structure.
Egg whites
Whipped to a foam that traps air, giving the candy its light, airy texture.
Karo syrup
Keeps the sugar from crystallizing, producing a smoother, less grainy candy.
Rolled nuts
Add texture and crunch throughout the candy.

The step that matters

Continue beating until nearly cold. Beating the hot sugar syrup and egg white foam as it cools lets the sugar crystallize into fine crystals and set the foam. Dropping the candy too early can leave it runny, while waiting too long can make it hard to spoon.

Swap the nuts

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

  1. Chestnutfits better
  2. Almondfits better
  3. Hazelnutfits better
  4. Nutsthe original

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