Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set gently over low heat, giving it richness.
- Egg whites
- Add lightness and body to the custard as they set with the heat.
- Cream
- Adds fat for a smooth, rich texture and a silkier mouthfeel.
- Milk
- Forms the liquid base that the eggs thicken into a pourable custard.
- Loaf sugar
- Sweetens the custard and balances the richness of the cream and yolks.
The step that matters
Stir the mixture over low heat until it begins to thicken. Egg proteins set at moderate temperatures, so high heat or lack of stirring can curdle the custard into grainy lumps. Gentle heat and constant stirring keep it smooth.
Swap the coriander
How well each one fits the dish's main ingredients (milk, lemon, cinnamon, almond, sugar, cream, egg):
- Nutmegfits better
- Cardamomfits better
- Gingerfits better
- Corianderthe original
Fit is the average pairing score against milk, lemon, cinnamon, almond, sugar, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
