Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Forms the fruit base layer, providing bulk and a tart, fruity flavour.
- Egg yolk
- Thickens the custard as it heats, giving it a smooth, set texture.
- Sweet cream
- Adds richness and fat, giving the custard a smooth, creamy mouthfeel.
- Milk
- Forms the liquid base of the custard, which thickens when heated with the yolk.
The step that matters
Scalding the custard without boiling. Egg yolks thicken as they heat but curdle if they boil. Stirring constantly over low heat keeps the custard smooth and evenly thickened.
Swap the apple
How well each one fits the dish's main ingredients (lemon, sugar, milk, cream, egg):
