Who says you can’t cook fish in a microwave? I have proven time and again that it’s not only possible, it may even be a good idea. Some microwave ovens come with a steaming function. It may be a programmable function, but I normally go by eyeballing. Watch your fish closely, turn it a couple of times during the cooking process and your fish could be done just right.
Always make sure you have your seasoning sauce in the plate as you microwave. A dry plate is unlikely to give you good results. This is a HK style “steamed” fish. The ingredients in the seasoning are simply white pepper, light soy sauce, sugar and water.
