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 structure as they set with heat.
Flour
Thickens the milk mixture so the custard holds its shape when sliced.
Egg whites
Whipped into a stiff foam that forms a light topping which browns in the oven.
Milk
Forms the liquid base of the custard, giving it body and a soft texture.
Sugar
Sweetens the custard and helps the topping brown.

The step that matters

Boil the custard until thickened. Flour and egg yolks only thicken when the mixture reaches a full boil. If it stays underheated, the custard stays thin and may not set properly once cooled and layered.

Swap the banana

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

  1. Vanillafits better
  2. Raisinfits better
  3. Figfits better
  4. Bananathe original

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