Understanding Rhubarb
What Is Rhubarb?
Rhubarb is a perennial vegetable often treated as a fruit in culinary applications. Known for its bright red stalks and tart flavor, rhubarb is a staple in pies, jams, and sauces. Though the stalks are edible, the leaves are toxic and must be discarded before cooking.
When Is Rhubarb in Season?
Rhubarb season typically runs from April to June, though some varieties may produce into early summer. Fresh rhubarb stalks should be firm and brightly colored, ranging from deep crimson to light pink with occasional green streaks.
Ingredients for Homemade Rhubarb Pie
To make a traditional rhubarb pie, you’ll need a few simple ingredients, many of which may already be in your pantry. Here’s what you’ll need:
- 4 cups fresh rhubarb, chopped into 1/2-inch pieces
- 1 1/3 cups granulated sugar (adjust to taste)
- 1/4 cup all-purpose flour (for thickening)
- 1 tablespoon butter (to dot on top before baking)
- 1/4 teaspoon ground cinnamon (optional, for added warmth)
- 1 egg + 1 tablespoon water (for egg wash)
- 2 pie crusts (homemade or store-bought)
For Homemade Pie Crust (Optional)
- 2 1/2 cups all-purpose flour
- 1 teaspoon salt
- 1 cup unsalted butter, cold and cubed
- 68 tablespoons ice water
Preparing the Pie Crust
Step 1: Mix the Dough
In a large bowl, mix flour and salt. Cut in cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs. Slowly add ice water, one tablespoon at a time, until the dough just comes together. Avoid overmixing.
Step 2: Chill the Dough
Divide the dough into two discs, wrap in plastic wrap, and refrigerate for at least 30 minutes. This rest period allows the gluten to relax and the butter to chill, resulting in a flakier crust.
Making the Rhubarb Filling
Step 1: Mix Rhubarb with Sugar and Flour
In a large mixing bowl, combine chopped rhubarb, sugar, flour, and cinnamon if using. Gently stir to coat the rhubarb pieces evenly. Let this mixture sit for 1520 minutes to allow the juices to start releasing.
Step 2: Taste and Adjust
Rhubarb’s tartness can vary, so taste a small piece of raw rhubarb with sugar to check if the sweetness level suits your preference. Add a little more sugar if your rhubarb is particularly sour.
Assembling the Pie
Step 1: Roll Out the Dough
Roll one dough disc on a floured surface into a circle about 12 inches wide. Place it in a 9-inch pie plate, pressing gently into the bottom and sides. Trim any excess dough hanging over the edge.
Step 2: Add the Filling
Spoon the rhubarb filling into the crust, spreading it out evenly. Dot the top with small pieces of butter to enrich the filling as it bakes.
Step 3: Add the Top Crust
Roll out the second dough disc. You can place it whole on top for a traditional covered pie or cut it into strips for a lattice-style crust. Seal the edges by crimping with a fork or your fingers. Cut slits into the top crust to allow steam to escape if using a full cover.
Step 4: Apply Egg Wash
Whisk one egg with a tablespoon of water and brush it over the top crust for a glossy, golden finish.
Baking the Pie
Step 1: Preheat and Bake
Preheat your oven to 400°F (200°C). Place the pie on a baking sheet to catch any drips. Bake for 20 minutes at this high temperature to set the crust, then reduce heat to 350°F (175°C) and continue baking for 3035 minutes, or until the filling is bubbling and the crust is golden brown.
Step 2: Cool the Pie
Let the pie cool for at least two hours on a wire rack. This resting time allows the filling to thicken properly and makes slicing cleaner and easier.
