04 - Pour the honey, balsamic vinegar glaze, salt, and black pepper over the onion and around the pan.
05 - Remove the pan from heat. Cover with the puff pastry sheet, trimming excess edges and creating a slight pleat by pressing sides together. Seal edges with a fork.

01 - The tatin can be prepared up to 2 hours ahead and reheated briefly before serving for optimal texture.
