Summer is the on-season for processing sweet bamboo shoots. I made some pickled bamboo shoots. River snails and pork bones are stewed for hours to make a delicious stock. A handful of rice noodles, a few slices of vegetables, pickled bamboo shoots and green beans, chunks of "wood ear" fungus and dried daikon radish. Just before serving, sprinkle it up with pan-fried peanuts and tofu skin, and add a spoonful of chili oil. Sour, pungent, savory, mouthwatering, and steaming - this is how a bowl of Liuzhou "Luosifen", the legendary cuisine that has been listed as one of the intangible cultural heritages of China, is made.
