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: 2-nonenal (fatty, green).

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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

Milk
Provides the liquid base and milk solids that give the custard its body.
Sugar
Adds sweetness and lowers the freezing point, keeping the ice cream softer.
Cream
Adds fat, which makes the ice cream richer and smoother in texture.

The step that matters

Cool the custard completely before adding cream and freezing. A warm base freezes slowly and forms large ice crystals, giving a coarse, icy texture. Chilling the custard first lets the ice cream freeze quickly and smoothly in the machine.
