Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper to prevent sticking.
On a lightly floured surface, roll out the thawed puff pastry to smooth any creases. Cut the pastry into 12 equal strips, about 1 inch wide.
Take one strip of puff pastry and place a teaspoon of cranberry sauce at one end. Add a few small pieces of Brie cheese on top of the cranberry sauce. If using honey, drizzle a little over the Brie for added sweetness.
Fold the pastry over the filling, sealing the edges. Then, twist the strip from both ends in opposite directions to form a spiral. Place each twisted pastry on the prepared baking sheet. Repeat with the remaining strips.
Brush each twist lightly with the beaten egg. Sprinkle chopped fresh or dried rosemary over them, followed by a pinch of sea salt for extra flavor.
Bake the twists in the preheated oven for 15-20 minutes, or until they are golden brown and puffed.
Remove from the oven and let cool slightly before serving. These twists are delicious warm or at room temperature.
