Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Yolks thicken the custard as they heat, and beaten whites add lightness and structure.
Milk
Forms the liquid base that the eggs set into a smooth, tender custard.
Corn starch
Thickens the milk as it heats, giving the custard a firmer body.

The step that matters

Cook in a tin pail over warm water or a double boiler. Gentle, indirect heat lets the egg proteins set slowly into a smooth custard. Too much heat can curdle the eggs and leave the custard grainy.
