Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the custard and the ice cream's body.
- Eggs
- Thicken the custard as they cook, giving the ice cream a smooth, rich texture.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer.
- Chocolate
- Provides the main flavor and, melted smooth, adds richness to the base.
- Cream
- Adds fat, which makes the frozen ice cream creamier and less icy.
The step that matters
Stirring the egg mixture into the scalded milk. Eggs can scramble if the heat is too high or they are added too quickly. Stirring constantly keeps the custard even so it thickens smoothly instead of curdling.
