Why it works: Vanilla and milk 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
Prepare
Split the vanilla bean and boil it in a little milk until the flavor is extracted, then strain.
Mix the arrow-root powder with enough cold milk to make a thin paste, rubbing until smooth.
Make the custard
Boil the cream and milk together, then stir in the arrow-root mixture and the strained vanilla milk.
Once it boils hard, remove from heat and stir in powdered sugar; bring to a boil again.
Freeze
Strain the mixture and pour it into a freezer, surrounded by finely broken ice mixed with coarse salt.
Beat the cream hard for half an hour, scraping down the sides occasionally.
When well frozen, transfer to a mold, surround with fresh salt and ice, and freeze again.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Adds richness and fat, giving the frozen ice cream a smooth, creamy texture.
- Milk
- Provides the liquid base and dairy solids that give the ice cream its body.
- Arrow-root powder
- Starch that thickens the base and helps keep the frozen texture smooth.
- Powdered sugar
- Adds sweetness and softens the frozen texture, so it stays scoopable.
- Vanilla bean
- Supplies the vanilla aroma and flavor, extracted into the milk.
The step that matters
Boiling the arrow-root mixture into the cream and milk. Starch thickens only when heated to a boil, and it must be stirred in smoothly. Lumps or insufficient heat leave a grainy or thin base that freezes poorly.
