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 as they set with heat and add richness.
- Sugar
- Adds sweetness and helps balance the richness of the eggs and milk.
- Milk
- Forms the liquid base of the custard.
- Corn starch
- Thickens the milk as it heats, giving the custard body.
The step that matters
Return the mixture to the saucepan and cook over low heat until thickened. Egg yolks can curdle or scramble if overheated. Cooking gently over low heat lets the custard thicken smoothly as the starch gelatinizes and the yolk proteins set.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, milk, corn):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Dillfits less well
Fit is the average pairing score against egg, sugar, milk, corn. Candidates are from the same food group and used in at least 100 recipes.
