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

What each ingredient does

Gelatin
Sets on cooling into a firm, sliceable gel that holds the custard's shape.
Milk
Forms the liquid base, and its proteins add body and richness.
Eggs
Egg proteins set on heating, thickening the custard and giving it structure.
Sugar
Adds sweetness and softens the firmness of the set.
Vanilla
Adds aroma without changing the set.

The step that matters

Returning the custard to a boil after adding the yolks. Egg yolks thicken as they heat, but overheating can curdle them. Removing the custard immediately once it boils keeps it smooth and lets the eggs set evenly.
