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 custard
Heat the milk in a tin pail over boiling water until it boils.
Stir in the cornstarch and boil for about 3 minutes.
Add the beaten eggs and heat just until scalded.
Stir in the sugar and vanilla.
Strain the mixture through a wire sieve.
Let the mixture cool completely, then pour it into a freezer.
Freeze
Pack layers of coarse sea salt and ice around the freezer until full.
Stir rapidly until the mixture hardens.
Stir more gently until well frozen.
Drain off excess water.
Pack again with ice and salt.
The ice cream will be ready to serve in about 2 hours.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Forms the creamy base of the ice cream.
- Eggs
- Add richness and help thicken the custard as they heat.
- Cornstarch
- Thickens the milk so the mixture sets smoothly when frozen.
- Sugar
- Sweetens the base and lowers the freezing point for a softer texture.
The step that matters
Heat the eggs just until scalded. Overheating beaten eggs can curdle the custard, leaving a grainy texture. Heat gently and stop once the mixture is scalded, just below boiling.
