Rinse edamame and dry very well with clean tea towel or paper towels.
Put the edamame in a bowl.
Combine sesame oil, mandarin juice, tamari, ginger and chili powder in a cup and mix. Pour over edamame and shake until coated well. Scoop out edamame with a slotted spoon or put in a sieve over the trash to get rid of extra liquid before adding to air fryer.
On “Air Fry” setting at 400 degrees cook for five minutes and then shake the edamame around. Add another 5-8 minutes, depending on how brown you want them. Watch very closely at ten minute mark to prevent burning.
Remove from air-fryer and sprinkle salt and sugar on top. This step is optional.
