Use either a live redfin culter or black carp, split the fish in half, and nail it to a board. Use a knife and scrap off the meat, leaving the bones and spine on the board. Chop the meat until fine, mix with lard and bean starch,1 then stir the mixture with one’s hand. Add a little salt water, but do not use light soy sauce. Add green onion and ginger juice, and form the mixture into balls. When this is done, place them in boiling water to cook. Scoop them out when done, and let them rest in a bath of cold water.2 When they are ready to be served, boil them with chicken broth and laver.3
1 I’m still wondering if “豆粉” (doufen) is bean starch or bean vermicelli, since both can be used in fish balls. The ambiguity stems from the fact that 粉 (fen) can either be used to mean starch, or one of the many Chinese pasta products made from starch. I’m going with the former since it’s a more common ingredient when making fish balls.
2 This is a very accurate and detailed description of the fish-ball-making process. Definitely one of the better recipes noted-down by Yuan Mei.
3 The laver described here is a type of red algae likely from Genus Porphyra
