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

What each ingredient does

Butter
Creamed with sugar, it adds richness and a tender crumb.
Sugar
Sweetens the cake and helps hold air when creamed with butter.
Flour
Forms the structure that holds the cake together as it bakes.
Magic baking powder
Releases gas during baking so the cake rises and becomes light.
Eggs
Beaten whites trap air and set during baking, adding lift and structure.
Walnuts
Add crunch and a nutty flavour, with fat that enriches the crumb.

The step that matters

Folding in the beaten egg whites. Beaten whites hold the air that lifts the cake. Stirring them vigorously knocks air out, so they should be folded in gently and only until just combined.

Swap the walnut

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

  1. Almondfits better
  2. Chestnutfits about as well
  3. Milletfits about as well

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