Why it works: Sugar and cream 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
- Egg yolks
- Thicken as they heat and enrich the filling with richness and body.
- Sugar
- Sweetens the filling and adds body to the mixture.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Apples
- Add moisture and tart flavour to the filling.
The step that matters
Heating the egg yolk mixture in the double boiler. Egg yolks thicken as they warm, but they scramble if overheated or left unstirred. Constant stirring over gently simmering water keeps the heat even and the filling smooth.
Swap the apple
How well each one fits the dish's main ingredients (egg, sugar, lemon, cream):
- Vanillafits better
- Raspberryfits better
- Orangefits better
- Applethe original
Fit is the average pairing score against egg, sugar, lemon, cream. Candidates are from the same food group and used in at least 100 recipes.
