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 frothy foam that forms the light, airy topping of the dessert.
Currant jelly
Adds sweetness and fruity flavor to the whipped egg white mixture.
Berry jam
Adds sweetness and fruity flavor to the whipped egg white mixture.
Sponge cake or naples biscuit
Forms the soft base layer that the frothy topping is heaped over.

The step that matters

Heap the frothy mixture high in the center of the dish. Egg white foam is made of air bubbles held in a thin film of protein; once beaten and sitting, it slowly loses volume and weeps liquid. Heaping it promptly keeps the peak height and light texture.

Swap the currant

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

  1. Vanillafits better
  2. Blueberryfits better
  3. Raspberryfits better
  4. Currantthe original

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