Gui Chai or Chinese Chive Dumplings is my all time favorite snack. I used to get up real early to go to an open-air market around our house with my mother.
There was a lady busy frying Chinese Chive Dumplings for her customers and there was always a long line at her stall. We would always stop at this Gui Chai stall and buy some for a snack before breakfast (only for me, I guess no one else snacked before breakfast). She made the best Chinese Chive Dumplings sauce I ever had. The sauce recipe is made from my memory.
