How to adjust
Temperature: about 20 °C (25 °F) below the oven setting. Time: start checking at 80% of the recipe time. Technique: don't overfill the basket, and shake or flip halfway — air needs to reach all sides.
Air fryers differ per brand and size, and small pieces cook faster than large ones. Treat this as your starting point and check early the first time you make a recipe.
