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

What each ingredient does

Strawberries
Provide the main flavour and fruit body of the dessert.
Gelatin
Sets the mixture so it holds its shape when chilled.
Egg whites
Beaten in to trap air, giving the sponge its light, airy texture.
Sugar
Sweetens the dessert and helps stabilise the beaten foam.

The step that matters

Adding the egg whites. Egg whites must be beaten into the cooled, thickened mixture so they trap air without collapsing. If the mixture is still warm, the gelatin may not set properly and the foam can deflate, so the cooling beat matters.

Swap the lemon

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

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