Put the frozen mud carp fillet in the lower rack of the fridge to defrost overnight. Wash them and dry them up.
Peel the fillets and cut them into pieces. Puree them and mix them up with marinade materials evenly. Put them in the fridge for at least 30 minutes
Cut the end of the mushrooms and clean up the surface with a paper towel. Cut them up into half and cut them into criss cross pattern
Put the cornstarch on the mushrooms and fill it up with the fillets.
Fry each side with 2 tbsp of oil on low heat until it becomes golden. Set aside.
Put the sauce in the wok on medium heat. After the sauce starts to bubble, put the mushroom and add the lid for about 1 minute. Serve.
Notes
1. In order to make the fillets more solid and easily put on the mushroom, we put the fillets in the fridge after marinating and crush them into pieces.
