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

What each ingredient does

Tart apples
Provide the main body and tart flavor of the apple islands.
Eggs
Whites are beaten to lighten the apple mixture; yolks enrich the custard and help it set.
Cream
Adds richness and body to the boiled custard.

The step that matters

Add the beaten egg whites. Beaten egg whites hold air only when whipped to the right stiffness and folded in gently. Overmixing deflates them, leaving the apple islands dense instead of light.

Swap the currant

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

  1. Strawberryfits better
  2. Pearfits better
  3. Vanillafits better
  4. Currantthe original

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