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 ↓
Vanilla Ice Cream
Ingredients
Directions
Make the custard
In a saucepan, heat the milk over a double boiler.
Mix the corn starch with a little cold milk and stir it into the hot milk.
Cook until it boils for 2 minutes, then add the sugar.
Beat the egg yolk with a spoonful of cold milk and stir it in, cooking until thickened but do not let it boil.
Remove from heat and strain through a thin cloth.
Cool the mixture in a pan of cold water for a few minutes.
Finish and freeze
Beat the egg white with ½ teaspoon sugar until stiff and fold it into the cooled custard.
Stir in the cream and vanilla, then pour the mixture into an ice cream freezer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the milk custard so it becomes smooth and creamy when cooled.
- Egg yolk
- Thickens the custard and adds richness as it cooks gently.
- Egg white
- Whipped to stiffness, it folds in air for a lighter, softer texture.
- Sweet cream
- Adds fat and richness, giving the frozen ice cream a smooth, creamy mouthfeel.
- White granulated sugar
- Sweetens the custard and lowers the freezing point, keeping the texture soft.
The step that matters
Cook the egg yolk gently without boiling. Egg yolk proteins set when heated, but if the custard boils they can curdle and turn grainy. Cooking only until thickened keeps it smooth.
