Chinese Stem Mustard Tuber

Chinese Stem Mustard Tuber is a bright green, knobby, fist-sized, swollen fleshy stem of a mustard plant that has a satisfying crunch and great versatility! This cool season crop grows large 3 1/2 - 5 inch-diameter stems that can be sliced into fried rice and tofu dishes or it can be harvested for its delicious mustard greens to flavor soups and stir-fries. Originating from the Sichuan Province of China, mustard tuber is often pickled with salt and red hot chili paste to make a kimchi-like side, called "Zha Cai," to add a delicious pop of flavor to rice congee and noodles.
