The fishball is an edible, ball-shaped patty made of pulverized fish. It is somewhat flat in shape and most often made from the meat of cuttlefish or pollock and served with a sweet and spicy sauce or with a thick black sweet and sour sauce. Fish balls in the Philippines are sold by street vendors pushing wooden deep frying carts. The balls are fried then served skewered, and most often offered with a choice of dipping sauces. You can buy this at two pesos per 3 pcs. The one above I already cooked in the house and made the sauce.
