Sugar and apple barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set when gently heated, giving it body.
- Milk
- Forms the liquid base of the custard that the eggs thicken.
- Sugar
- Adds sweetness to the custard.
- Apples
- Provide the main body and flavour once baked and pureed.
- Egg whites
- Folded into the puree to lighten its texture.
The step that matters
Cooking the custard over low heat. Egg proteins thicken the milk only within a narrow temperature range. Heating too fast or leaving it unstirred can scramble the eggs and leave lumps, so constant stirring over low heat keeps the custard smooth.
Swap the apple
How well each one fits the dish's main ingredients (milk, egg, sugar):
- Vanillafits better
- Figfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
