The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and apple barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Egg whites
Whipped into a foam that gives the float its light, airy structure.
Sugar
Sweetens the whites and helps stabilise the whipped foam.
Apples
Provide fruit flavour and moisture to the airy foam.
Soft custard
Forms the smooth, creamy base layer beneath the apple foam.

The step that matters

Beat the egg whites until stiff. Whites must be whipped until stiff so they trap air. Under-whipped whites stay loose and deflate when the apple is mixed in, losing the light texture the float depends on.

Swap the apple

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

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonfits better
  4. Applethe original

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