Why it works: Sugar and cream 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 ↓

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.

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.
