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

What each ingredient does

Milk
Provides the liquid base and dairy proteins that set into the custard.
Eggs
Proteins coagulate on gentle heating, thickening the liquid into a soft custard.
Sugar
Adds sweetness and helps keep the custard tender and smooth.

The step that matters

Cook until the custard thickens, stirring constantly. Egg proteins set when heated, but overheating or leaving the mixture still causes the eggs to scramble and curdle. Constant stirring and gentle heat in a water bath keep the custard smooth and evenly thickened.
