Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs thicken the custard base when heated, giving the ice cream body and richness.
- Sugar
- Caramelized sugar adds deep, toasted flavor and sweetness to the base.
- Rich cream
- Adds fat, which makes the frozen ice cream smooth and creamy rather than icy.
- Sweet milk
- Forms the liquid base of the custard, adding moisture and milky sweetness.
The step that matters
Cook the custard in the double boiler until it thickens. Gentle, indirect heat lets the egg proteins set slowly and thicken the custard without curdling. Overheating causes the eggs to scramble, which gives a grainy texture.
