Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Caramelized sugar gives the ice cream its deep, toasty, bittersweet flavour.
- Milk
- Forms the liquid base that the custard is cooked in and later frozen.
- Egg yolks
- Thicken the base as they cook and add richness to the custard.
- Flour
- Helps thicken the mixture and gives it a smoother body during cooking.
- Rich cream
- Adds fat and richness, giving a smooth, creamy texture after freezing.
The step that matters
Cook the mixture until it boils. Egg yolks and flour thicken the base as it heats, but overheating can scramble the eggs and leave lumps. Heating gently and stirring keeps the custard smooth before it is cooled and frozen.
