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

What each ingredient does

Prunes
Provide the main sweet, moist fruit body of each layer.
Ground nuts
Add richness and texture between the prune layers.
Egg whites
Whipped to stiff foam, they form the light, airy topping.
Powdered sugar
Sweetens the egg whites and helps stabilize the whipped foam.
Lemon juice
Adds acidity that helps stabilize the beaten egg whites and brightens the sweetness.

The step that matters

Beating the egg whites until stiff. Egg whites must be beaten until they hold stiff peaks; under-beaten whites stay runny and collapse, while the acid from the lemon juice helps the foam hold its structure. Fat or yolk residue in the bowl can also stop whites from whipping fully.

Swap the nuts

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

  1. Pistachiofits better
  2. Milletfits better
  3. Almondfits better
  4. Nutsthe original

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