Yaki Gyoza (Japanese pan fried dumplings)

I first encountered steamed dumplings during a backpacking trip to China. My Mandarin wasn't what it should be, so I did what you’d expect from every linguistically challenged Brit - I pointed at a few things on the menu and hoped for the best. I was very pleased with myself…until I found out mine were filled with "twice fried goose gizzards"...  These are better, I promise!
