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

What each ingredient does

Egg whites
Beaten whites form a thin coating that dries into a crisp, glossy icing shell on the fruit.
Finely powdered sugar
Sugar coats the fruit and dries with the egg white into a sweet, crisp, opaque icing.

The step that matters

Put the pan in a cooling oven until the icing firms. The oven must be cool enough that the egg white dries and sets without browning or puffing. Too much heat can cook the coating unevenly or brown it.

Swap the currant

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

  1. Vanillafits better
  2. Apricotfits better
  3. Figfits better
  4. Currantthe original

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