Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs or egg yolks
- Proteins set as they heat, giving the filling its thick, custard-like structure.
- Cake flour
- Starch swells in the hot milk, thickening the filling and keeping it smooth.
- Milk
- Forms the liquid base that the eggs and flour thicken into a custard.
- Sugar
- Adds sweetness and balances the richness of the eggs and milk.
The step that matters
Cooking in the double boiler. Egg proteins can curdle or scramble if the mixture gets too hot too fast. Gentle, constant stirring over indirect heat lets the starch and egg thicken evenly into a smooth custard.
