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
In a double boiler, combine the shaved chocolate, ⅓ cup water, and sugar. Cook until smooth, stirring occasionally.
Add the milk and bring to a boil.
In a separate bowl, mix the flour with a small amount of milk to form a smooth paste, then add it to the boiling mixture.
Finish and freeze
Once cool, fold in the whipped cream and add vanilla to taste.
Freeze the mixture until solid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main chocolate flavor and color of the ice cream.
- Milk
- Adds liquid and milk solids that give the base body and creaminess.
- Cream
- Adds fat that makes the frozen texture rich and smooth.
- Sugar
- Sweetens the base and lowers its freezing point for a softer scoop.
- Flour
- Thickens the boiled mixture so it holds together and feels less icy.
The step that matters
Thickening the flour paste. Flour must be mixed smoothly into a paste with cold or cool milk before adding it to the boiling mixture; otherwise it clumps and stays lumpy, and the starch only thickens properly once it is heated and dispersed evenly.
