My ultimate dumplings - Gyoza

I don't even know how many dumplings I've made over the past 10 years. Maybe over 10,000??? This dish became my "ultimate" dish and everybody just loves it. I don't put anything special - grand pork, Asian chives and soy sauce. Nothing else, just those three things but it turns out something very special. Crispy outside, tender and moist inside. I always make a lot and freeze them, so this is also our convenient frozen food (a.k.a. "I need to make something quick. or I don't know what to make tonight. Help me!" dish) that we always have in our freezer.
