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 that thickens into a soft, creamy custard.
Eggs
Thicken the custard as they set, giving it structure and a smooth body.
Sugar
Sweetens the custard and balances the richness of the eggs and milk.

The step that matters

Remove from heat after one minute. Egg proteins set at moderate heat and can curdle or scramble if overcooked, so timing the removal from heat keeps the custard smooth and soft.
