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
- Thicken the mixture as they heat and set, giving the filling its body.
- Sour cream
- Adds moisture and a tangy richness that keeps the filling soft.
- Almonds
- Contribute nutty almond flavor and a fine, slightly grainy texture.
- Sugar
- Sweetens the filling and balances the tang of the sour cream.
The step that matters
Cooking the custard over medium heat while stirring constantly. Egg proteins set and thicken the mixture, but if it gets too hot or is left unstirred, the eggs can curdle or scramble, leaving a grainy, lumpy filling.
Swap the almond
How well each one fits the dish's main ingredients (cream, sugar, egg):
- Almondthe original
- Pistachiofits about as well
- Chestnutfits less well
- Pecansfits less well
Fit is the average pairing score against cream, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
