There is no one definitive answer to this question, as there are many different ways to prepare unrobed eels. However, one popular method is to simply marinate the eels in a mixture of soy sauce, rice wine vinegar, and sesame oil, before pan-frying or grilling them.
Skin and bone the eels, scald and slice.
Put the slices into a mixture of egg white, cornstarch and seasonings, stir-fry in 50% heated oil.
Slice bamboo shoots, fragrant mushrooms and green peppers, stir-fry in 80% heated oil, add the sliced eels and cooking wine, toss a few times.
