The flavor team

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: ethyl caproate (fruity, apple peel).

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

What each ingredient does

Egg yolks
Thicken the custard and add richness through their proteins and fat.
Gelatin
Adds body and helps the frozen ice cream hold its shape and resist melting.
Cream
Adds fat, which makes the ice cream smooth and rich in texture.
Sugar
Adds sweetness and lowers the freezing point, keeping the ice cream scoopable.
Milk
Provides the liquid base that the custard is built on.

The step that matters

Heat the custard until it comes to a boil. Egg yolks thicken as they heat, but they can scramble if overheated. Heating just to a boil and then removing from heat thickens the custard while limiting curdling, which keeps the base smooth before freezing.

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