Prune Pie

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the prunes

  1. Soak the prunes in cold water until fully swollen.

  2. Stew the prunes in water to cover until very tender.

  3. Press the prunes through a strainer and flavor with lemon or pineapple, sweetening to taste.

Make the filling

  1. Beat 2 eggs for each cup of strained prunes and mix with ½ cup cream.

  2. Stir the egg and cream mixture into the prunes.

  3. Fold in the stiffly beaten egg whites.

Assemble and bake

  1. Make a rich pastry.

  2. Line a pie tin with the pastry.

  3. Pour the prune mixture into the pastry.

  4. Bake at 400°F (200°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Prunes
Provide the main body, sweetness and flavor of the filling once softened and strained.
Eggs
Set the filling when baked and add richness and structure to the smooth prune mixture.
Cream
Adds fat and softness, giving the filling a smoother, richer texture.

The step that matters

Fold in the stiffly beaten egg whites.. Whites trap air when whipped, giving lightness. Folding gently keeps that air in, so the filling bakes up light rather than deflating and becoming dense.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Strawberryfits about as well
  4. Lemonthe original

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