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 and add richness and a smooth texture as they set.
Cornstarch
Thickens the milk mixture into a smooth, stable cream when heated.
Milk
Forms the liquid base of the cream that the yolks and cornstarch thicken.
English walnuts
Add chopped nut texture and a rich, toasty flavor to the cream.

The step that matters

Cook over medium heat, stirring constantly until thickened. Egg yolks can curdle or scramble if overheated, and cornstarch needs to reach a boil to reach full thickening. Constant stirring spreads heat evenly and prevents lumps and scorched spots on the pan bottom.

Swap the walnut

How well each one fits the dish's main ingredients (egg, sugar, milk):

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