I really respect Iron Chef Chen as a chef. He seems to be a wonderful mentor to many young chefs working under him. He caught my attention as a Iron Chef Chinese on Iron Chef TV program and really enjoyed watching him improvise many recipes. I learned a lot just by watching and copied many of his ideas from the show that I now incorporate into my cooking repertoire. Since then, I've looked for his cookbooks and found 4 in Japanese language. I love all his recipes, especially his famous Mapo Tofu or Mapo Doufu. His dad was a pioneer in introducing Szechuwan cooking to Japanese and he is known as a father of Mapo Doufu in Japan because he was apparently the first Chinese man to cook something so spicy as this dish in Japan. It is now very famous in Japan and Iron Chef Chen Kenichi continues with that tradition at his restaurants in Japan. I wish Chinese and Japanese sauces and other culinary ingredients are known in the West for their proper Chinese and Japanese names like most Indonesian or Malasian sauces ie sambal olek etc instead of using generic names such as bean sauce, etc because it can get very confusing using those generic names. For this dish, you need two Chinese sauces/pastes http://www.foodsubs.com/CondimntAsia.html#bean%20sauce. The first one is Chinese brown bean sauce/paste aka tenmienjan, tenmenjan, or tenmenjiang - it's made from soy beans and sometimes is called Chinese miso type sauce or sweet noodle sauce. It is dark brown in color and has a wonderful dark miso type flavor. The next sauce is Chinese chili bean sauce aka toubanjan or doubanjiang - it has soy beans along with hot chilies and is red color. Don't use regular hot red chili sauce since it lacks the complexity of soy beans found in hot bean red chili sauce. The other two Chinese ingredients you will need for this recipe are fermented black beans (you can usually find these bagged and are ready to use or in bottles) and Szechuwan peppercorn. Szechuwan pepeprcorn is optional though Chef Chen does use it. Chef Chen uses regular tofu (not firm or silken) for his recipe. If you cannot find green garlic chives also known as nira in Japanese, I would use combination green onion and garlic. You want the taste of garlic as well as color of green onion for this dish. Another item that he uses is Japanese chili pepper known as ichimi tougarashi ie crushed or minced red pepper and if you cannot buy this item easily, I would substitute by mincing Chinese, Japanese, Thai, or Korean dry red pepper. This is a very, very spicy version of Mapo Tofu and if you like, cut down on chili pepper and chili oil if you like this recipe milder. However, this dish goes so well with plain steamed white rice that you can eat and eat while your nose is running. I plan to post another of Chef Chen's milder Mapo Tofu recipe using Hoisin sauce in the future.
