Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Lemon Ice Cream
Ingredients
Directions
Prepare
Use sour cream that has soured quickly.
Cut the lemon rind thin and steep it in ½ cup of sweet cream over boiling water for 10–15 minutes.
Strain the mixture, cool it, and add it to the rest of the ingredients.
Freeze
Put the mixture in a freezer and set it in ice for 1 hour before freezing.

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.

Shared aroma: acetic acid (sour, vinegar).
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
- Sour cream
- Gives a tangy flavour and a rich, creamy body to the base.
- Sweet cream
- Adds fat for a smooth, rich texture and carries the lemon flavour.
- Sugar
- Adds sweetness and keeps the frozen ice cream softer and scoopable.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Lemon rind
- Contributes fragrant lemon oils that give aroma and depth of flavour.
The step that matters
Chilling the mixture before freezing. Cooling the base thoroughly before freezing helps it freeze quickly. Quick freezing forms smaller ice crystals, giving a smoother texture. A warm base freezes slowly and can turn grainy.
Swap the lemon

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