Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the custard, giving it body and moisture.
- Egg whites
- Cook into light, spongy islands that set and float on the custard.
- Egg yolks
- Thicken the custard as they heat, giving it richness and a smooth texture.
- Whole egg
- Adds more protein to the custard, helping it thicken when gently heated.
- Sugar
- Sweetens the custard and balances the richness of the eggs and milk.
The step that matters
Cook the whites gently. Egg whites set through gentle heat. Cooking them too hard or too long makes them tough and rubbery and can cause them to shrink or weep. Turning them once helps them cook evenly on both sides.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
