Let’s get cooking! Here’s how you can bring this tart to life:

1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Roll out the puff pastry on a lightly floured surface to smooth out any creases. Transfer it to the prepared baking sheet.
3. Using a sharp knife, score a border about 1 inch from the edges of the pastry. Be careful not to cut all the way through.
4. Place slices of brie evenly within the scored border.
5. In a small saucepan over medium heat, combine cranberries, honey, and sugar. Cook until the cranberries begin to pop and the mixture thickens, about 5-7 minutes.
6. Spread the cranberry mixture over the brie slices.
7. Sprinkle the diced pancetta and thyme leaves over the top. Season with a pinch of salt and pepper.
8. Brush the edges of the pastry with the beaten egg to ensure a golden crust.
9. Bake for 20-25 minutes, or until the pastry is golden brown and puffed.
10. Let the tart cool slightly before slicing. Enjoy while warm!

Pro tip: Don’t worry if some cranberries escape or if your pastry puffs unevenly. It’s all part of the charm!
