Prune 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

  1. Line a pie plate with the rich crust.

  2. Turn the stewed and sifted prunes into the crust and sweeten slightly.

Make the topping

  1. In a bowl, beat the butter with the sugar, bread crumbs, and egg yolks until well combined.

  2. Gently fold in the whipped egg whites until just mixed.

  3. Spread the mixture over the prunes.

Bake

  1. Bake in a moderate oven at 350°F (175°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 fruit flavor and moist, soft filling beneath the topping.
Egg whites
Whipped to add lightness and help the topping rise and set in the oven.
Egg yolks
Enrich the topping and help it set into a tender, custard-like texture.
Bread crumbs
Soak up moisture and give the topping body so it holds its shape.
Butter
Adds richness and a tender texture to the topping.

The step that matters

Gently fold in the whipped egg whites. Folding rather than stirring keeps the air in the whipped whites. That air gives the topping its lift, so overmixing will leave it dense and flat.
