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

What each ingredient does

Eggs
Set the custard as their proteins coagulate when heated, giving it structure.
Milk
Provides the liquid base and moisture that makes the custard smooth and creamy.
Flour
Thickens the mixture so it holds a firmer, less runny texture as it cooks.
Sugar
Adds sweetness to the custard.

The step that matters

Cook until a custard forms. Egg proteins set with heat, but if the heat is too high or cooking goes too long, the eggs can curdle and turn grainy. Cooking gently in a water bath and stopping once it thickens keeps the texture smooth.
