Hi, nice article! You can also try kefir, really easy to make and very healthy, mushrooms are available on taobao. When I lived in Shaanxi Province I was making three kinds of cheese, but for that, I think I need fresh milk, I`ll try to anyways, as I find life hard without my domestic products :) Sour cream is possible to get from yogurt, but for that you should use milk with 3% of fat, I guess, the taste is really nice. Is it possible to buy fresh goat milk here in Kunming?
