Banana Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the crust

  1. Bake the pie crust and let it cool.

Make the custard

  1. In a saucepan, heat the milk.

  2. Mix the sugar, flour, and salt, then stir into the milk.

  3. Add the beaten yolks of the eggs and cook until thick.

  4. Let the custard cool.

Assemble and bake

  1. Slice the bananas and place them in the crust.

  2. Pour the custard over the bananas.

  3. Frost with the beaten egg whites and sprinkle with sugar.

  4. Brown in the oven at 350°F (175°C).

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 as they cook and add richness to it.
Egg whites
Form a light frosting that sets and browns in the oven.
Flour
Thickens the custard so it holds its shape when sliced.
Milk
Forms the liquid base of the custard.
Bananas
Provide the fruit layer and their sweetness and flavor to the filling.

The step that matters

Cook the custard until thick. Egg yolks and starch must be heated enough to thicken the custard, but overheating can curdle the eggs. Stop once it coats a spoon.

Swap the banana

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

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

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