In terms of traditional cutting, both northern and southern knives are used in Haizhou, reflecting that Haizhou has been one of the coastal channels for north-south exchanges in the past century; in terms of roasting, seed-based medicines such as fenugreek are usually stir-fried with a broom, cucumber cream is unique in China, and the roasting of white radish is also a local feature. Solid auxiliary materials are stir-fried, such as elephant skin with sand, donkey-hide gelatin with clam powder or cattail pollen, etc. In addition to the currently popular wine, vinegar, salt, ginger juice, honey, and sesame oil, goat blood, whole blood, and black bean juice are also commonly used for liquid auxiliary materials. These all reflect the product characteristics of Haizhou, which is backed by mountains, faces the sea, and is surrounded by rivers.
