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 that thickens and sets into the custard.
- Flour
- Its starch thickens the custard as it heats.
- Eggs
- Proteins set when heated, firming the custard and adding richness.
- Sugar
- Adds sweetness and balances the flavor.
The step that matters
Pouring the beaten eggs and stirring briskly. Egg proteins set at fairly low heat, so if the eggs meet overly hot liquid or sit still, they can scramble or curdle. Stirring briskly spreads the heat evenly and keeps the custard smooth.
Swap the lemon
How well each one fits the dish's main ingredients (milk, sugar, flour, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against milk, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
