I tried to prepare store bought frozen gyoza once and, well, the result wasn't pretty. Gyoza are life though and as much as i love biking, crossing half of the city to get a good batch isn't always time efficient.
Today i realized i could try to prepare them in the air fryer. Wish me luck.

update: 14 minutes at 200°C with a bit of water sprinkled in for steaming did the job (maybe 12 would have been better). they were alright. biggest mistake was that i served them way too hot, so i don't actually know whether their taste was acceptable enough.
