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 ↓
Raspberry Ice Cream
Ingredients
Directions
Make the raspberry base
Combine raspberries, 6 oz. sugar, lemon juice, and ½ cup water in a porcelain-lined pan, then bring to a boil for 2 minutes.
Strain the mixture through a fine sieve and set aside to cool.
Make the custard
Boil the milk.
Beat the egg yolks with 2 oz. sugar in a bowl.
Pour the boiling milk over the yolks, stirring vigorously.
Return the mixture to the saucepan and heat gently until thickened, but do not boil. Set aside to cool.
Combine and freeze
Mix the cooled fruit puree with the custard and add carmine for color.
Pour into a quart mold and freeze until solid.

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
- Raspberries
- Provide the main flavor and fruit puree that gives the ice cream its color and taste.
- Egg yolks
- Thicken the custard and add richness and a smooth, creamy texture.
- Milk
- Forms the creamy base that the custard is made from and gives body to the ice cream.
- Sugar
- Sweetens the dish and lowers the freezing point so the ice cream stays softer when frozen.
- Lemon
- Adds acidity that brightens the raspberry flavor.
The step that matters
Heat the custard gently without boiling. Egg yolks thicken as they warm, but if the custard boils they can scramble and turn grainy. Heating gently until it coats a spoon keeps it smooth.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, milk):
- Vanillafits better
- Figfits about as well
- Raisinfits about as well
- Lemonthe original
Fit is the average pairing score against sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
