Meatballs or basso are types of meat balls that are commonly found in Indonesian cuisine. Bakso is generally made from a mixture of ground beef and tapioca flour, but there are also meatballs made from chicken, fish, or shrimp and even buffalo meat. In the presentation, meatballs are generally served hot with a clear gravy broth, mixed with noodles, vermicelli, sprouts, tofu, sometimes eggs and sprinkled with fried onions and celery. Meatballs are very popular and can be found all over Indonesia; from street hawkers to big restaurants. Various types of meatballs are now widely offered in the form of frozen food sold in supermarkets or malls.
