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 as they set with gentle heat.
Egg whites
Whip into stiff peaks to form a light, airy topping.
Cornstarch
Thickens the milk mixture so the custard becomes smooth and firm when cooked.
Milk
Forms the liquid base of the custard.
Bananas
Provide the fruit base and sweet, soft flavor under the custard.

The step that matters

Stir the custard over heat until thick. Egg yolks and cornstarch thicken only with gentle, steady heat. Too much heat can curdle the eggs, while too little leaves the custard runny.

Swap the walnut

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

  1. Almondfits better
  2. Pecansfits better
  3. Hazelnutfits better
  4. Walnutthe original

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