Equipment
- Medium saucepan
- Baking sheet
- Parchment paper
- Sharp Knife or Pizza Cutter
- Fork
- Small bowl
Ingredients
For the Rhubarb Filling
- 2 cups chopped rhubarb Fresh is best, but frozen (thawed and drained) works beautifully too.
- 1/2 cup granulated sugar Feel free to adjust to your sweetness preference.
- 1 tbsp cornstarch
- 1 tbsp lemon juice
- 1/4 tsp vanilla extract optional
For the Pockets
- 1 sheet puff pastry Store-bought, thawed according to package directions.
- 1 egg beaten, for egg wash
- powdered sugar optional, for dusting
Instructions
- Step 1: Prepare Rhubarb Filling: In a medium saucepan, combine your chopped rhubarb, granulated sugar, cornstarch, lemon juice, and if you're using it, the vanilla extract. Place it over medium heat and stir occasionally. You'll notice the rhubarb starting to break down and the mixture thickening up – this usually takes about 5-7 minutes. Once it's jammy and beautiful, take it off the heat and let it cool down completely. This is key! A cool filling prevents your puff pastry from getting soggy.
- Step 2: Preheat Oven: While your filling is chilling out, go ahead and preheat your oven to a cozy 375°F (190°C). Grab a baking sheet and line it with parchment paper.
- Step 3: Prepare Puff Pastry: On a lightly floured surface, carefully unroll your thawed sheet of puff pastry. Using a sharp knife or a pizza cutter, cut it into squares or rectangles, roughly 4x4 inches.
- Step 4: Fill Pastry Pockets: Spoon a generous dollop of your cooled rhubarb filling right into the center of each pastry square. Don't overfill, or it might bubble out during baking. Now, gently fold one side of the pastry over the filling to meet the other side, forming a neat little pocket. Press the edges together firmly to seal the filling inside. For that classic, beautiful finish, use the tines of a fork to crimp all around the edges.
- Step 5: Brush with Egg Wash: Whisk up that egg in a small bowl to create your egg wash. Lightly brush the tops of all your assembled pockets.
- Step 6: Bake: Carefully transfer your pretty pockets to your prepared baking sheet. Pop them into the preheated oven and let them bake for about 15-20 minutes. You're looking for them to be wonderfully puffed up and golden brown. Every oven is a little different, so keep an eye on them!
- Step 7: Serve: Once they're out of the oven, let them cool on the baking sheet for a few minutes. They'll be hot! If you want to add an extra touch of sweetness and beauty, dust them generously with powdered sugar before serving. They’re absolutely delightful warm, but honestly, they’re still fantastic at room temperature too.
Notes
For best results, keep puff pastry cold and ensure the rhubarb filling is completely cooled before assembling to prevent sogginess. Avoid overfilling and firmly crimp the edges to seal. The rhubarb filling can be prepared a day or two in advance. Feel free to customize these pockets by swapping rhubarb with other fruits like apples or berries (adjusting sugar accordingly), adding spices like cinnamon or ginger, including a dollop of sweetened cream cheese, or sprinkling with chopped nuts. Instead of powdered sugar, a simple glaze can be drizzled. Store leftovers in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. Reheat in a 300°F oven for 5-10 minutes or a toaster oven for 1-2 minutes to restore crispness; freezing baked pockets is not recommended.
