Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the sharp acidity and bright citrus aroma that define the sherbet.
- Sugar
- Adds sweetness and keeps the frozen texture softer by lowering the freezing point.
- Milk
- Adds body and a mild dairy flavor that softens the tart lemon.
- Arrowroot or cornstarch
- Thickens the milk so the frozen mixture stays smooth and less icy.
- Egg whites
- Add airy structure and lightness to the frozen mixture.
- Fresh cream
- Adds fat for richness and a smoother, creamier mouthfeel.
The step that matters
Stir in the thickened milk and egg whites at the right moment. Adding them once the lemonade begins to freeze lets them blend into a partly set base. Added too early or too late, the milk and whites are harder to distribute evenly, which affects smoothness and texture.

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