Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set, giving it a rich, smooth body.
- Egg whites
- Add lightness and help the custard set with a delicate texture.
- Cream
- Provides fat and richness, giving the custard its smooth, creamy texture.
- Pounded sugar
- Sweetens the custard and helps form a crisp caramel layer on top.
- Arrowroot or flour
- Thickens the custard so it holds its shape when stirred over heat.
The step that matters
Stir over low heat until thickened like custard. Egg proteins set at moderate temperatures, and high heat can curdle the eggs into a grainy texture. Gentle, constant stirring keeps the custard smooth.
Swap the arrowroot
How well each one fits the dish's main ingredients (cream, lemon, sugar, egg, orange):
- Arrowrootthe original
- Asparagusfits about as well
- Sweet potatofits about as well

Fit is the average pairing score against cream, lemon, sugar, egg, orange. Candidates are from the same food group and used in at least 100 recipes.
