Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Form the bulk of the dish, adding moisture, body and fruity flavor.
- Egg whites
- Beaten, they add air and a light, fluffy structure to the apple mixture.
- Pulverized sugar
- Sweetens the apples and dissolves easily into the mixture.
- Milk
- Forms the liquid base that the egg yolks thicken into a custard.
- Egg yolks
- Thicken the hot milk through gentle heat, giving the custard a smooth, rich body.
The step that matters
Stirring the egg yolks into the boiling milk. Egg yolk proteins set when heated, so in boiling milk they can scramble into lumps. Adding the yolks gradually and keeping the heat controlled helps the custard stay smooth and thickened.
Swap the apple
How well each one fits the dish's main ingredients (sugar, egg, milk):
- Vanillafits better
- Figfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
