Take slices of black carp or a grouper, season with autumn sauce, then add starch powder and egg white. Start a wok and stir-fry them over high heat. Plate them using a small dish and add green onions, Szechuan pepper, and soy-pickled ginger. Each dish should not contain more than six liang of fish, since heat cannot be evenly and thoroughly applied when there is too much ingredients.
魚片
取青魚、季魚片，秋油郁之，加芡粉、蛋清，起油鍋炮炒，用小盤盛起，加蔥、椒、瓜薑，極多不過六兩，太多則火氣不透
Notes:
This recipe is quite similar to the preparation of our contemporary stir-fried fish slices (炒魚片), which shows how old this method of fish preparation likely is. Although some recipes contain more ingredients than this, regardless the core technique for stir-frying the fish is the same.
While stir-frying fish slices (likely stir-frying itself) sounds easy to do, all too often the fish slices gets cooked into jerky by the novice cook or stirred until it disintegrates into something more like fish floss. Successful preparation of this dish takes some skill and a few tricks. First the fish’s flesh needs to be sliced with its grain so the pieces does not easily fall apart. Next, the fish must be first quickly pan fried in a wok to set their shape before being quickly and gently flipped until the fish is barely cooked. The cooking typically takes less than a minute or so. Any other ingredients that goes into the dish must be precooked to not mess up this timing.
When done well, the resulting dish is sublime.
