Step1:Pick two living Portunus from the market. Because it's sea crab. There are few living in the inland area. You can also eat the fresh one. But the taste is not as good as the living one. You can't eat a river crab when it's dead. Open the lid. Remove the cheek and other things inside. Wash and cut.
Step2:Heat the pot. Pour in some oil. Stir in the onion, ginger and garlic. Stir in the portunus and stir fry. Add the cooking wine to remove the fishy smell. Stir fry for a while. Add in the soy sauce and oyster sauce. Add water and boil until boiling.
Step3:Put the rice cake in the pot. Cook until it tastes good. Put some salt when you leave the pot. Because oyster sauce and soy sauce are salty. Only a small amount of salt is enough.
Step4:Collect the juice in a big fire. Dish it. Open it. Delicious.
