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 carries the flavor.
Eggs
Egg yolks thicken the custard as they heat, while whipped whites add a light topping.
White sugar
Sweetens the custard and helps stabilize the beaten egg whites.

The step that matters

Stir the yolk mixture into the boiling milk. Egg yolks can scramble if they meet very hot milk too fast or are not stirred constantly. Adding them gradually while stirring, and keeping the custard heated only until it thickens, helps it stay smooth and silky.
