Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the filling into a custard as they cook, giving it body and structure.
- Heavy cream
- Adds richness and a smooth, tender texture to the filling.
- Granulated sugar
- Sweetens the filling and helps it thicken smoothly as it cooks.
- Lemon juice
- Adds acidity that brightens the sweet apple flavor.
- Apple sauce
- Forms the main body of the filling and supplies apple flavor and moisture.
The step that matters
Cook the mixture until thickened. Eggs thicken when heated, but overcooking can make them curdle or turn grainy. Cook gently and stop once the filling coats a spoon so it sets smoothly rather than scrambling.
Swap the apple
How well each one fits the dish's main ingredients (sauce, egg, cream, lemon, sugar):
- Vanillafits better
- Raspberryfits better
- Orangefits better
- Applethe original
Fit is the average pairing score against sauce, egg, cream, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
