Pickled mustard, also known as preserved mustard, suan cai, and sour vegetable, are a staple food in many parts of Asia. Pickled mustard is actually a misnomer as the greens are not pickled but rather fermented in a manner that is similar to sauerkraut. Preserved mustard has a distinct flavor and aroma along with a salty and sour taste. Preserved mustard is often chopped and used as an ingredient, eaten as a appetizer, and used to top congee.
Uses: Chop pickled mustard and add it to your stir-fried dishes such as fried rice and pad thai. Top plain foods such as porridge or congee with this flavorful vegetable. Eat mustard as a palate cleanser during your meal.
