Why it works: Lemon and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Lemon Ice

Ingredients

Directions

Make the syrup

  1. Boil water and sugar together until well dissolved and skimmed.

Infuse and strain

  1. Let the mixture cool, then add lemon juice and sliced rind.

  2. Allow to infuse for 1 hour.

  3. Strain the mixture into a freezer.

Freeze

  1. Once it begins to freeze, add the beaten egg whites.

  2. For a creamier texture, add milk or cream after it starts to freeze, using less water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar
Dissolved in boiling water to sweeten the ice and keep it soft after freezing.
Lemon juice
Provides the sharp acidity that defines the flavour of the ice.
Lemon rind
Adds aromatic oils and a more intense lemon flavour during infusion.
Eggs
Whites are beaten and folded in to add air and a lighter, smoother texture.
Milk or cream
Adds fat, which gives a creamier, softer texture to the frozen result.

The step that matters

Adding the beaten egg whites once the mixture begins to freeze. If the mixture is fully frozen, the whites cannot be evenly incorporated, so the ice stays dense instead of light. Adding them at the start of freezing lets them distribute and trap air as the mixture firms up.

Swap the lemon
