When icefish1 are freshly caught from the water, they are known as “savoriness of ice”. Braise them in chicken broth with dried-cured ham. Alternatively, stir-fry them for a more tender fish. For the dried item, soak them in water until soft. They make a good dish when stir-fried with diluted soy sauce.2
1Although the direct translation of the Chinese name is the somewhat ambiguous “silver fish”, the fact that Yuan Mei indicates this fish looks like ice tells use that it is most likely Salanx prognathus or Salanx chinensis, one of the species among a genus of Asian “ice fish”. These fish are quite interesting in that the adults retain much of the features present in a fish’s larval or juvenile stages. They are small, translucent, largely cartilaginous, and look amazingly like whitebait (and sometimes mistaken as such). They are also sometimes known as “noodle fish” since its form and texture resemble the small thick rice noodles. It goes to show that when you think you’ve seen all the wonders of nature, nature throws living rice noodles your way.
2I’m not sure what is jiangshui (醬水), or “watered sauce”. Could it soysauce and water or diluted soysauce, or just liquid extracted from a wet bean sauce? Either way it’ll likely taste like the former, hence the translation.
