Step-by-Step Instructions

1. Prepare the dough: Combine flour, sugar, and salt in a large bowl. Cut in cold butter using a pastry cutter or food processor until mixture resembles coarse crumbs. Add ice water and vinegar, mixing just until dough comes together. Form into a disk, wrap in plastic, and refrigerate for at least 1 hour.
2. Prepare the filling: Toss chopped rhubarb with sugar, cornstarch, lemon zest, vanilla, and salt. Let sit for 15 minutes to allow juices to release.
3. Preheat oven to 375°F (190°C) and position rack in the lower third of oven.
4. Roll the dough: On a floured surface, roll dough into a 12-inch circle about ⅛-inch thick. Transfer to tart pan, gently pressing into corners. Trim excess dough.
5. Blind bake: Line crust with parchment paper and fill with pie weights. Bake for 15 minutes, then remove weights and parchment. Bake another 5 minutes until lightly golden.
6. Add filling: Arrange the rhubarb mixture in the par-baked crust, spreading evenly. The rhubarb tart filling should be piled slightly higher in the center.
7. Bake: Return to oven and bake for 25-30 minutes until filling is bubbling and crust is golden brown.
8. Cool completely: Allow to cool on a wire rack for at least 2 hours before removing from pan and serving.

Tips, Variations & Cooking Advice

– Flavor enhancements: Add strawberries (replace 1 cup rhubarb with strawberries)
– Herbs: Try adding 1 tablespoon fresh thyme or basil to the filling
– Gluten-free option: Substitute a 1:1 gluten-free flour blend for the crust
– Vegan adaptation: Use plant-based butter and add 1 tablespoon ground flaxseed
Common Mistakes to Avoid

1. Using warm butter: Always use cold butter for the crust—it creates steam pockets that make the crust flaky
2. Overworking the dough: Mix just until combined to prevent tough crust
3. Skipping the blind bake: This crucial step prevents soggy bottoms
4. Using rhubarb leaves: Remember they are toxic and should always be discarded
5. Not letting it cool fully: Cutting too soon results in runny filling
Storage & Meal Prep Tips
– Room temperature: Store covered for up to 2 days
– Refrigeration: Keeps for up to 5 days in an airtight container
– Freezing: Not recommended for the whole tart, but unbaked crust can be frozen for up to 3 months
– Reheating: Warm individual slices in a 300°F oven for 10 minutes to restore crispness

FAQs
Can I use frozen rhubarb for this tart?
Yes, frozen rhubarb works well. Thaw completely and drain excess liquid before using. You may need to increase the cornstarch to 4 tablespoons.
Is it necessary to peel rhubarb?
No, peeling isn’t necessary for most rhubarb. If the stalks are particularly thick or fibrous, you can remove any stringy parts by gently pulling them away.
Can I make this tart ahead of time?
Yes! The crust can be made 2 days ahead and refrigerated. The whole tart can be baked a day in advance and stored at room temperature.
Why is my rhubarb filling too runny?
This typically happens if the tart isn’t cooled completely before slicing. Make sure to let it cool for at least 2 hours, or the cornstarch won’t fully set.
Can I reduce the sugar in this recipe?
You can reduce the sugar to ½ cup, but be prepared for a much tarter flavor. Consider adding 2-3 tablespoons of honey or maple syrup to maintain some sweetness.
