Blackberry & Brie Puff Pastry Roll

Preheat oven to 400°F. Stack 2 baking sheets on top of each other (this will help keep the bottom from burning) and line with parchment paper. Lay puff pastry on another sheet of parchment and roll it out to about 12 inches. Evenly spread jam over the pastry, leaving ½ inch of one edge bare for sealing. Lay Brie slices on top of the jam. Brush the bare edge with water to help it stick. Starting at the opposite edge, roll the pastry into a log; place seam-side down on a small cutting board and freeze until firm enough to slice, 20 to 30 minutes.

Using a sharp knife, cut the log into 10 pieces. Transfer the slices to the prepared baking sheet. Bake until golden brown on the edges, 23 to 25 minutes. Let cool for 10 minutes before serving.
