Rhubarb Pie

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Preheat the oven to 400°F (200°C).
Line a deep pie plate with the pie crust.

Fill and cover

Fill the plate halfway with rhubarb.
Add ½ cup sugar and cinnamon, then fill the plate with more rhubarb.
Top with the remaining sugar and butter.
Cover the pie with another layer of pie crust.

Bake and rest

Bake until the crust is golden brown.
Let the pie stand in the oven with the door open for 10 to 15 minutes.

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

What each ingredient does

Rhubarb: Forms the bulk of the filling and supplies the tart flavor that sugar balances.
Sugar: Adds sweetness, balances rhubarb's tartness, and draws moisture out to form a syrup.
Cinnamon: Adds warm aroma that complements the fruit.
Butter: Adds fat and richness to the filling as it melts over the fruit.
