We can't stop talking about these easy puff pastry tarts that are all over TikTok, so we decided to make a few different flavors ourselves. This clever recipe simplifies the concept behind tarte tatin, an upside-down tart where apples are caramelized in butter and sugar, then topped with pastry dough and baked. We're using spring produce to make Asparagus Prosciutto & Cheese Tarts, Strawberry Kiwi Tarts, and Blackberry Brie Tarts. This appetizer is so easy and fun to make – get creative with your toppings!
