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

Strawberries
Provide the main flavour and fruit body of the dessert.
Sugar
Sweetens the mixture and softens the texture by lowering the freezing point.
Egg white
Whipped into the nearly frozen mixture to add air and a lighter, smoother texture.
Lemon juice
Adds acidity that brightens the strawberry flavour and balances the sugar.

The step that matters

Add the egg white when the mixture is nearly frozen. If the mixture is fully frozen, the beaten egg white cannot blend in evenly and won't give the airy texture. Adding it near freezing keeps the mixture slushy enough to incorporate air, and slow freezing keeps ice crystals small.

Swap the lemon

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

  2. Raisinfits about as well

  4. Datesfits less well

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