Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the mixture as they set with gentle heat, giving the ice cream a rich, custard-like body.
- Milk
- Forms the liquid base that the eggs thicken and the freezer turns into ice cream.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer and scoopable.
The step that matters
Cooking the custard over low heat. Egg yolks set at moderate temperatures and can scramble if overheated. Gentle heat and constant stirring thicken the base smoothly without curdling.
