Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the milk mixture into a custard and add richness.
- Flour
- Helps thicken the custard so it holds its shape when sliced.
- Egg whites
- Whipped and spread on top, they set and brown into a light meringue topping.
- Sugar
- Sweetens the custard and the meringue topping.
- Butter
- Adds fat and richness to the custard.
The step that matters
Cooking the custard until thick. Stirring constantly over medium heat keeps the egg yolks and starch from scorching or lumping, and the custard must thicken fully before filling, since it will not firm up much further once cooled.
Swap the walnut
How well each one fits the dish's main ingredients (egg, milk, sugar, flour, butter):
- Almondfits better
- Chestnutfits about as well
- Milletfits about as well
- Walnutthe original
Fit is the average pairing score against egg, milk, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
