Then I had a brilliant thought, why not cook them in my power pressure cooker. I used my 10qt PPCXL I inserted the bottom rack. I then poured in enough water to cover the bottom just touching the rack approximately 1 1/2-2 Cups of water. I placed the frozen Gyoza on the rack and sprinkled them with a little sesame oil.
I then inserted the steaming rack and placed the frozen sauce packets on it.
I placed the lid on making sure my valve was closed and selected the Fish/Vegatable Steam button and time adjusted it to 4 minutes. When the timer finished I waited about a minute and did a quick release. The result were amazing the sauce packets were thawed and the Gyoza were cooked to perfection.
At this point you could very easily fry these but I didn't because I love them steam. I am so ecstatic that I now have a new way to cook my Gyoza that is fast & easy.
