Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Gelatine
Sets the liquid into a firm, sliceable structure as it cools.
Strawberries
Provide the main flavour, colour and moisture of the sponge.
Egg whites
Whipped into foam to give the sponge its light, airy texture.
Sugar
Sweetens the dish and balances the tartness of the fruit and lemon.
Lemon juice
Adds acidity that brightens the strawberry flavour.

The step that matters

Fold in the whipped egg whites. The gelatine mixture must be thickened but not set before the whites are folded in. If it is too cold or too firm, it will not blend evenly, and the foam will deflate or leave lumps, lowering the airy texture.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonthe original
  4. Figfits about as well

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