Apple Toaster Strudel

1 . Stage

Preheat oven to 400° and line a baking sheet with parchment. In a medium saucepan over medium-high heat, combine apples, brown sugar, raisins, walnuts (if using), lemon juice, cinnamon, and salt. Cook, stirring occasionally and adding 1/4 cup water if mixture looks dry, until apples have softened, 10 to 15 minutes. Let cool completely.

2 . Stage

On a clean surface, roll each puff pastry sheet to a 12"x10" rectangle. Prick sheets with a fork and cut into 16 (5"x3") rectangles. Arrange 8 rectangles on prepared sheet.

3 . Stage

In a small bowl, beat egg with a splash of water. Brush outer edges of pastry with egg wash. Place 2 heaping tablespoons filling in center of pastry. Place remaining 8 pieces of pastry on top and gently press with your fingers around the corners to seal. Trim pastry to form straight edges if they appear jagged. Brush top of pastry with egg wash.

4 . Stage

Place another piece of parchment over pastry and stack with a sheet tray. This will prevent the pastry from puffing up in the oven.

5 . Stage

Bake tarts until golden brown, 25 to 30 minutes. Let cool 30 to 40 minutes.

6 . Stage

In a small bowl or liquid measuring cup, whisk confectioners’ sugar and 5 teaspoons cold water. Drizzle each tart with glaze.
