Good morning from Taiwan!! The latest cookbook (and one of the very few in English exclusively on the topic) is my friend Cathy Erway's "The Food of Taiwan" (I recently reviewed it on my blog). I've purchased many cookbooks in Taiwan, but most are in Chinese. So far Cathy's is the only one that covers the most common dishes (beef noodles, oyster omelet, fried chicken, danzai noodles, three-cup chicken), culture / history notes about Taiwan (stinky tofu, night markets, the melding of cultural influences).
There is also an Australian cookbook, "Blue Eye Dragon," but I have not seen it / cooked from it.
