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

What each ingredient does

Granulated sugar
Provides the sweet base and, when boiled, the firm structure of the candy.
Karo syrup
Interferes with sugar crystallization, keeping the candy smooth and tender rather than grainy.
Egg whites
Whipped into foam, they give the candy its light, airy, aerated texture.
Walnut kernels
Add crunch and nutty flavor that contrast with the soft candy.

The step that matters

Pouring the hot syrup over the egg whites while beating. The syrup must be poured slowly into the whites while beating constantly. Pouring too fast or stopping the beater can deflate the foam or cook the whites unevenly, and the candy loses its light texture.

Swap the walnut

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

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

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