What do I need for air frying vs. deep frying?
When it comes to air frying, all you need is a countertop air frying appliance, or an oven/range that has an air frying feature. Simply plug your appliance into an outlet, apply a thin layer of oil, set your timer and wait for your food to cook.
For deep frying, you will not only need a deep frying appliance (a Dutch oven or pot might work, as well), but also two cups to two quarts of oil per cooking session. While it is possible to buy oil in bulk, deep fryers require significantly more oil each and every time.
