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 ↓
Frozen Custard
Ingredients
Directions
Make the custard
In a double boiler, combine egg yolks, milk, salt, and sugar to make a custard.
Cook until it reaches the right consistency, then let it cool.
Finish and freeze
Add the heavy cream, beaten egg whites, powdered sugar, and vanilla to the cooled custard.
Stir all ingredients together and freeze.

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 as they set gently over heat.
- Heavy cream
- Adds fat that makes the frozen texture smooth and creamy rather than icy.
- Egg whites
- Beaten whites add air, giving the frozen custard a lighter texture.
- Milk
- Forms the liquid base of the custard along with the yolks.
- Sugar
- Sweetens the custard and lowers the freezing point, keeping it softer when frozen.
The step that matters
Cook the custard to the right consistency. Egg yolks thicken as they heat, but overheating can curdle them into a grainy texture. Cooking gently in a double boiler and stopping once the custard coats a spoon keeps it smooth.
