How to make Colm O'Gorman's cracking cranberry and brie tartlets

Bite-sized Brie and Cranberry Tartlets
For this week’s party food recipe, I have paired homemade cranberry sauce with brie to make bite-sized Brie and Cranberry Tartlets.
I use shop-bought puff pastry for this recipe, after all, who has the time to make puff pastry from scratch, especially at this time of year?
