Creating these delightful Savory Cranberry and Brie Tartlets is simple when you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Prepare Puff Pastry: Roll out the puff pastry on a lightly floured surface. Cut it into squares or circles, depending on your tartlet preference.
3. Make the Filling: In a bowl, combine fresh cranberries, brown sugar, balsamic vinegar, thyme, salt, and pepper. Mix well until the cranberries are coated.
4. Assemble Tartlets: Place the pastry cutouts onto the prepared baking sheet. Add a few pieces of Brie cheese to the center of each pastry piece.
5. Add Cranberry Mixture: Spoon the cranberry mixture over the Brie on each pastry.
6. Fold Edges: Gently fold the edges of the pastry over the filling, leaving the center exposed.
7. Egg Wash: Beat the egg and brush it over the edges of the pastry for a golden finish.
8. Bake: Place the baking sheet in the oven and bake for 20-25 minutes, or until the pastry is golden brown and puffed.
9. Cool Slightly: Once done, remove the tartlets from the oven and let them cool for a few minutes before serving.

These steps will guide you in creating these delicious tartlets with ease.
