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 ↓

Add the cornstarch and sugar, then bring to a boil.
Quickly remove from heat and dissolve the chocolate in a little milk over low heat, stirring constantly.

Add the cream and vanilla, adjusting sweetness with more sugar if needed.
Chill and freeze
Chill the mixture and then freeze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the custard base and add richness and body to the ice cream.
- Cream
- Adds fat, which gives the frozen ice cream a smooth, rich texture.
- Cornstarch
- Thickens the custard base and helps keep the frozen ice cream smooth.
- Grated chocolate
- Provides the chocolate flavor and some fat that softens the frozen texture.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer.
The step that matters
Remove the custard from heat after it boils. Egg yolks scramble if overheated, which makes the base grainy. Removing it quickly after boiling and stirring the chocolate in gently keeps the custard smooth.
