Although Wanzhou grilled fish also adopts the roasting process, the focus is not only on simple roasting, but also on Chongqing specialty food, which is carefully cooked by combining pickling, roasting and stewing. It has long been separated from the ancient primitive string fire roasting method, and it was carefully studied with modern kitchen utensils. Wanzhou grilled fish retains the delicate flavor of fish to a great extent, and is cooked with various ingredients and herbs, so that grilled fish is no longer like the original method.
