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 filling

  1. Preheat the oven to 350°F (175°C).

  2. Chop the rhubarb and raisins together.

  3. Line a pie crust with the chopped mixture.

Assemble and bake

  1. Sprinkle sugar and flour over the filling.

  2. Dot with butter.

  3. Cover with another pie crust and bake until golden.

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

What each ingredient does

Rhubarb
Provides the tart acidity that balances the sweet sugar and raisins.
Sugar
Adds sweetness and helps draw moisture out of the fruit to form the filling.
Raisins
Add concentrated sweetness and chewy texture to the filling.
Eggs
Not used in the method, so role is left out.
Butter
Adds richness and fat, contributing flavor and browning to the crust.
