I was born (1932) and raised in China as a German, and immigrated to the US at the age of 15. I have many delicious food memories and have been able to recreate most of them in my kitchen here. There is one item that eludes me. I have tried and failed many times, and have not found any source to help me with this. Here is the background. I start by making sweet fermented rice wine using the wine yeast balls that can be obtained in most Chinese groceries. (If any one is interested in the process, I'll be glad to describe it.) The product of this fermentation in about 2-5 days is a sweet rice "soup" with a low alcohol content. Since no sweetener is used, the sweetness, as well as the alcohol, are created by the yeast. This step is easy. In the next step, the rice is strained from the liquid, and I assume that the rice is formed into round cakes and then, "magically," the cakes become covered with a sweet white bloom, almost a crust, and the inside is moist and sweet and delicious with just a hint of alcoholic residue. So far, my every attempt has ended up as moldy, vile garbage. I am searching for that "magic" process. Any suggestions?
