Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the custard as it cooks, giving the ice cream a creamy body.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream soft.
- Cream
- Adds fat, which makes the ice cream rich and smooth.
- Chocolate
- Provides the main flavor and adds fat for a smooth texture.
- Milk
- Forms the liquid base that the custard is built on.
The step that matters
Cook the mixture until it thickens into a soft custard. Egg proteins thicken as they heat, but overheating will scramble the egg and leave lumps. Cook gently and stop once the mixture coats a spoon.
