Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the milk into a smooth, spreadable cream as it cooks.
- Eggs
- Add richness and help set the cream as they cook with the milk.
- Milk
- Forms the liquid base that the cornstarch and eggs thicken.
- Sugar
- Sweetens the cream and softens its flavor.
- Butter
- Adds fat for a richer mouthfeel and smoother texture.
The step that matters
Stirring the cornstarch mixture while it cooks. Cornstarch thickens when heated, but it can settle and form lumps on the bottom of the pan if not stirred constantly. Constant stirring keeps the heat even and the cream smooth.
Swap the walnut
How well each one fits the dish's main ingredients (milk, egg, sugar, butter, lemon):
- Almondfits better
- Walnutthe original
- Pistachiofits about as well
- Pecansfits about as well
Fit is the average pairing score against milk, egg, sugar, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
