Popped the best popcorn by using ~1/4 cup of kernels spread out on an air-fryer basket.
1. Put airfryer basket on middle shelf
2. Turn another basket over and inserted into top shelf
3. Closed oven selected air-fry to 475 degrees fahrenheit.
4. When the oven hit 350 the kernels were all popped and perfect.
5. Hit cancel cooking
6. Ate some popccorn
Note: The other night I did it -- hit 375 temp. I am going to tweak a bit and then make a custom preset.
