Taylor Swift has developed an obsession with baking bread, particularly sourdough, which she admits has taken over her life. She makes various flavors such as blueberry, blueberry lemon, cinnamon swirl, cinnamon raisin, and funfetti sourdough and gifts them to her celebrity friends, including Jimmy Fallon. Fallon recently showcased his avocado toast recipe using Swift's signature sourdough, claiming it to be the best.

Fallon's avocado toast recipe is simple, vegan, and delicious, topped with mashed Hass avocado, sea salt, chili flakes, and olive oil. While Fallon uses Swift's sourdough in his recipe, those who do not have access to it can use a store-bought loaf or bake their own. Swift herself admits to being part of a sourdough community online, sharing her baking experiences and seeking feedback from friends.
