Step‑by‑Step Instructions for Best Rhubarb Lemon Pie
Step 1: Prepare the Crust
In a food processor, combine all-purpose flour, wheat flour, cardamom, sugar, and salt. Pulse until mixed, then add cold butter, mixing until crumbly. In a bowl, whisk together the egg yolk and milk, and then blend this mixture with the flour mixture until a dough forms. Chill the dough for 1 hour in the refrigerator to ensure a flaky crust.
Step 2: Pre-cook the Rhubarb
Preheat your oven to 350°F (175°C). In a baking dish, toss the chopped fresh rhubarb with sugar and ground cardamom. Cover with foil and bake for 20 minutes, then remove the foil and bake for an additional 5-10 minutes until the rhubarb is tender yet holds its shape. Allow it to cool while you prepare the crust and filling.
Step 3: Blind Bake the Crust
Preheat the oven to 375°F (190°C). Roll out the chilled dough on a floured surface to fit a pie pan, then transfer it to the pan. Line the crust with parchment paper, filling it with pie weights, and bake for 13-17 minutes until lightly golden. Once baked, remove from the oven and let the crust cool slightly before adding the filling.
Step 4: Blend the Filling
In a blender, combine sugar, yogurt, eggs, lemon zest, and fresh lemon juice. Blend until the mixture is smooth and creamy, ensuring there are no lumps remaining. This zesty lemon filling will complement the roasted rhubarb perfectly. Set the filling aside while you assemble the pie.
Step 5: Assemble the Pie
Spread the cooled rhubarb evenly across the bottom of the baked pie crust. Carefully pour the blended lemon filling over the rhubarb, ensuring that it covers all the fruit evenly. The filling should reach just below the crust edge, leaving a little space for expansion as it bakes.
Step 6: Bake the Pie
Carefully place the assembled pie in the oven and bake at 375°F (190°C) for 20-25 minutes. The filling should be set with a slight jiggle in the center when done. Keep a close eye on it to prevent overbaking, as the filling will firm up more as it cools.
Step 7: Cool and Serve
Remove the pie from the oven and let it sit at room temperature for 2-3 hours to cool completely. For the best texture, refrigerate the pie for at least an hour before slicing. Serve chilled, topped with whipped cream or vanilla ice cream to elevate the flavors of this Best Rhubarb Lemon Pie.
