An excellent summer dish when the hot weather dampens your appetite for meat. If dried shrimp are not available, 1-2 ounces of minced ham can be used as a substitute. Also, many other vegetables, such as Chinese cabbage, spinach, snow peas, bean sprouts, and so on, can be used instead of broccoli. Although they are not difficult to make, fish cakes do require a little time. You can always make them in two stages: You can either make up the fish paste in advance and refrigerate it for a while, or you can make the paste into fish cakes and then keep them in the refrigerator for 1 or 2 days before cutting them into finger-sized pieces and frying.
