Ingredients:
- 2 ½ cups all-purpose flour
- 1 tsp salt
- 1 tbsp sugar
- 1 cup unsalted butter, chilled and cubed
- 6-8 tbsp cold water
- 4 cups rhubarb, chopped into 1-inch pieces
- 1 cup granulated sugar
- 3 tbsp cornstarch
- 1 tsp vanilla extract
- 1 tsp ground cinnamon
- 1 tbsp lemon juice
Instructions:
- Combine flour, salt, and sugar in a bowl. Cut in butter using a pastry cutter until it resembles coarse breadcrumbs. Gradually add cold water until a dough forms. Shape into a disc, wrap in plastic, and chill for 30 minutes.
- In a mixing bowl, toss rhubarb with sugar, cornstarch, vanilla, cinnamon, and lemon juice. Let sit for 15 minutes to release juices.
- Preheat oven to 425°F (220°C). Roll out half of the chilled pastry on a floured surface to fit the pie dish. Place the pastry in the dish and fill with rhubarb mixture.
- Roll out the remaining dough and place over the filling, crimping the edges to seal. Cut slits in the top for steam to escape.
- Place in the preheated oven and bake for 20 minutes. Reduce temperature to 350°F (175°C) and bake for an additional 25 minutes until crust is golden and filling is bubbling.
- Allow the pie to cool for at least 30 minutes before slicing. Serve warm or at room temperature.
