Blackberry 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 filling

  1. Mix flour with sugar, then add blackberry juice, cream, and beaten egg yolks.

  2. Line a deep dish with thinly rolled pastry.

Bake

  1. Fill the pastry with the mixture and bake at 400°F (200°C) until the crust is set.

  2. Continue baking at 300°F (150°C) until the filling is thick and firm.

  3. Beat the egg whites with a pinch of salt until stiff, then spread on top and bake until browned.

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

Flour
Thickens the filling as it heats, giving it a firm, sliceable body.
Eggs
Egg yolks thicken the filling while the whites whip into a stiff, browned topping.
Cream
Adds richness and moisture, producing a softer, silkier filling.
Sugar
Sweetens the filling and helps it set with the egg proteins.
Blackberry juice
Provides the main fruit flavour, colour and liquid for the filling.

The step that matters

Continue baking at 300°F (150°C) until the filling is thick and firm.. Egg proteins set gradually as the filling heats. Baking too hot can curdle or puff the custard and leave it weeping, so the lower temperature lets it set smoothly.

Swap the blackberry

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