Check out the Ninja Crispi Portable Glass Air Fryer, an intriguing twist on the air fryer that's a perfect option for air frying your favorite frozen snacks at your next potluck—it'll help you win the day by frying up a batch of wings at your buddy's house. Basically, every other air fryer works by circulating hot air through a purpose-built, egg-like basket. But the genius of the Crispi is that its glass fryer tray doubles as a serving tray and a sealable fryer dish. The heating element and fan live in a hat-like unit with clamps that attach to heat-shock-resistant borosilicate glass frying baskets with ceramic-coated trays inside. While the actual “fry” setting can be a little intense, the “bake” setting works perfectly for softer foods like veggies.
