Why it works: Lemon and sugar 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 ↓
Lemon Ice Cream
Ingredients
Directions
Make the base
Steep the rinds of the lemons in 2 quarts of water for some time, then strain the mixture.
Add 2 lbs of white sugar and the whites of 24 eggs to the strained mixture.
Beat the mixture until it adheres to the bowl.
Churn
Churn in an ice cream maker until the consistency is like snow.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Lemon and sugar 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
- Lemon rinds
- Infuse the water with lemon aroma and flavour.
- White sugar
- Sweetens the mixture and softens the texture of the frozen cream.
- Egg whites
- Whipped by beating, they add foam and airy structure to the base.
- Lemon juice
- Adds sharp acidity that brightens the sweetness.
The step that matters
Beat until it adheres to the bowl. Beating incorporates air into the egg whites and sugar mixture, creating foam that gives the finished ice cream its light, airy texture. Under-beating leaves it dense.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- 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.
