Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

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
- Egg whites
- Whipped to a stiff froth, they add air and a light, smooth texture to the ice cream.
- Sugar
- Sweetens the mixture and lowers the freezing point, keeping the ice cream soft rather than rock hard.
- Currant juice
- Provides the main fruit flavor and liquid base of the ice cream.
- Lemon juice
- Adds acidity that brightens the tart currant flavor.
The step that matters
Adding the egg mixture to the partially frozen base. If the base is fully frozen, the whipped egg whites cannot blend in evenly and the air they hold is lost. Stopping at half frozen lets the foam fold in and keeps the texture light.
Swap the currant
How well each one fits the dish's main ingredients (sugar, lemon, egg):
- Orangefits better
- Vanillafits better
- Limefits better
- Currantthe original
Fit is the average pairing score against sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
