Why it works: Sugar and cream 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
Make the custard base
Scald the milk in a saucepan.
Gradually add the sugar and eggs, mixing well.
In a small bowl, mix the cocoa powder with a little milk until smooth, then add to the mixture.
Beat the mixture for a moment, then place it over low heat.
Stir constantly until the mixture thickens, then remove from heat.
Cool and freeze
Let it cool completely, then stir in the heavy cream.
Pour the mixture into an ice cream maker and freeze according to the manufacturer's instructions.

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 cook and add richness to the base.
- Heavy cream
- Adds fat for a smooth, creamy texture in the frozen ice cream.
- Sugar
- Sweetens the base and helps keep the frozen ice cream soft.
- Unsweetened cocoa powder
- Provides the chocolate flavour and colour.
- Whole milk
- Forms the liquid base that the eggs thicken and the cream enriches.
The step that matters
Stir constantly until the mixture thickens. Egg proteins can scramble if the custard overheats over low heat, leaving it grainy. Constant stirring spreads the heat evenly so it thickens smoothly.
