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 and whites add airy structure, while both help the dessert set.
Gelatin
Provides the gel that lets the cooled mixture hold its shape when set.
Milk
Forms the liquid base that gives the custard its body and moisture.
Sugar
Sweetens the custard and softens the set texture slightly.
Vanilla
Adds aroma and a rounded flavor to the milk-and-egg custard.

The step that matters

Stir the custard over hot water until it thickens. Egg proteins set with gentle heat, so overheating or rushing the stirring can scramble the yolks and leave the custard grainy instead of smooth.
