Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Chocolate Ice Cream
Ingredients
Directions
Prepare the base
Boil the milk in a double boiler.
In a bowl, mix flour and 1 cup of sugar.
Add eggs and beat until light.
Make the custard
Stir this mixture into the boiling milk and cook for 20 minutes, stirring often.
In a small saucepan, combine chocolate, 4 tablespoons sugar, and 2 tablespoons hot water, and stir over heat until smooth.
Add the chocolate mixture to the cooking mixture.
After 20 minutes, remove from heat.
Stir in the remaining sugar and cream gradually.
Freeze
Let cool, then freeze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they heat, giving the ice cream body.
- Flour
- Stabilises the custard so it thickens smoothly and resists curdling.
- Chocolate
- Provides the main flavour and some richness.
- Cream
- Adds fat for a rich, smooth texture.
- Milk
- Forms the liquid base that the custard is cooked in.
- Sugar
- Sweetens the mixture and keeps the frozen texture softer.
The step that matters
Cook the custard with frequent stirring. Eggs and flour thicken as they heat, but uneven heat or too little stirring can scramble the eggs or leave lumps. Stirring often keeps the heat even so the custard stays smooth.
