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

What each ingredient does

Gelatine
Sets the mixture as it cools, giving it a firm, sliceable body.
Egg whites
Whipped foam adds air and a light, airy texture to the mixture.
Sugar
Sweetens the mixture and balances the sharpness of the lemon.
Milk
Forms the base of the custard, adding richness and a creamy texture.
Lemon rind
Adds bright citrus aroma and a light acidic note.

The step that matters

Fold in the egg whites before the mixture sets. Gelatine firms as it cools, so the whites must be folded in while the mixture is still fluid. If it sets first, the whites cannot blend evenly and the airy foam is lost.

Swap the lemon

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

  1. Figfits better
  2. Peachfits better
  3. Blueberryfits better
  4. Lemonthe original

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