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 ↓
Chocolate Ice Cream
Ingredients
Directions
Make the chocolate base
Finely chop the chocolate and place it in a saucepan with 4 tablespoons of cold water.
Set the saucepan in a pan of boiling water and stir until it forms a smooth paste.
Stir in the milk and sugar.
Thicken the custard
Mix the corn starch with a little cold milk and stir it in; cook until it boils for 2 minutes.
Beat the egg yolk with 1 teaspoon of cold milk and stir it in; cook until it thickens without boiling.
Remove from heat and strain through a fine cloth into a bowl.
Set the bowl in a pan of cold water to cool.
Finish and freeze
Beat the egg white with ½ teaspoon of sugar until stiff and fold it into the mixture.
Add the cream and vanilla; if not cold enough, place in the freezer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main flavour and colour of the ice cream.
- Corn starch
- Thickens the custard base so it holds a smooth, creamy body.
- Egg
- Yolk thickens the custard, while the beaten white adds lightness when folded in.
- Sweet cream
- Adds richness and fat, giving a softer, creamier texture.
- White granulated sugar
- Sweetens the base and helps keep the ice cream soft when frozen.
The step that matters
Cooking the egg yolk custard without boiling. Egg yolk thickens as it heats, but if it boils it can curdle and become grainy. Cook gently and stop once it thickens.
