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

What each ingredient does

Eggs
Whipped whites give the cake lift and an airy, light crumb; yolks add richness.
Butter
Creamed with sugar, it traps air and adds fat for a tender texture.
Flour
Provides the structure that holds the cake together as it sets.
Sugar
Sweetens the cake and helps cream with butter to hold air bubbles.
English walnut kernels
Add crunch, nutty flavor, and some fat to the crumb.

The step that matters

Fold in walnut pieces and whipped whites gently. Folding keeps the air trapped in the whipped egg whites, so the cake stays light instead of dense after steaming.

Swap the walnut

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

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

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