You’ve finally purchased your first air fryer. Let me start by saying, I’m so happy for you. This small countertop convection oven is about to be your new favorite appliance. It won’t replace your other ones—the oven, toaster, and stovetop are fit for certain purposes—but it delivers on speed and crispiness like no other. It can cook with microwave-like speed (some meals 50% to 75% faster) without compromising on the quality of the finished dish, and it can recrisp some leftovers to a state arguably better than when it was fresh.
