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 ↓
Ice Cream
Ingredients
Directions
Make the base
Scald the milk in a saucepan, but do not boil.
In a bowl, whisk the egg yolks with the sugar and corn-starch.
Combine the scalded milk with the egg mixture, stirring well.
Finish and freeze
In a separate bowl, whip the egg whites until stiff peaks form.
Fold the whipped egg whites into the milk mixture.
Add the cream and flavor with vanilla or lemon.
Freeze the mixture until firm.

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 base and add richness as they cook gently with the milk.
- Egg whites
- Whipped to stiff peaks, they add airiness and lightness to the frozen texture.
- Cream
- Adds fat, which makes the frozen ice cream smooth and creamy rather than icy.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer when frozen.
- Corn-starch
- Helps thicken the egg and milk mixture and stabilizes the custard against curdling.
The step that matters
Scald the milk without boiling. Milk that is scalded gets hot enough to help the base thicken later, but boiling can scorch it and make the egg mixture more likely to curdle when combined.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
