Literally translates as" "pock-marked old lady tofu." For more background see Daydream's recipe (which is very different from this one) "recipe #78452" A simpler version from some of the others I have seen on this site. This version is adapted from a Chinese cookbook that my Mandarin tutee gave me as a college graduation gift--"Chinese Cooking" from JG press. It is very helpful to have all of your ingredients prepared and ready to go before you start the wok because it goes very fast from that point on! Where it calls for 'hot bean sauce' I use tobanjan/lajiaojiang (chili bean paste), 'Lan Chi' (lanji in pinyin) brand, but the recipe says you can also substitute two dried red chiles. You can experiment with different tofu to see what keeps its shape the best; I have personally found that the semi-firm, locally made fresh tofu that I can get at the Uwajimaya here holds up well. This recipe reminds me of the tofu that I used to order at one of my favorite restaurants in Shanghai.
