This is a baby food that my mother used to cook for me when I was young. I can't think of it as too long ago, but my mother says that I like seafood because I eat a lot of fish and baby food. I made it after researching the combination of flounder and vegetables. A halibut is a white fish rich in protein, vitamins, and calcium. Flounder, which is often used as a baby food for fish, is good because it is light and has less fishy taste. Among the white fish that are commonly used in baby food, it is relatively safe to expose heavy metals and can be easily obtained as non-frozen creatures. If you steam it with onions or ginger to remove the fishy taste, the fishy taste disappears. Also, cabbage is a vegetable that makes our baby's bones strong because its calcium absorption rate is as high as milk. It helps digestion, does not burden your stomach, and is rich in dietary fiber, so it is good for preventing constipation. Cabbage that can be obtained throughout the year increases calcium absorption and goes well with white fish. Also, oyster mushrooms are rich in dietary fiber when boiled with onions, so they are good for cholesterol reduction, so I added them together. I added a little bit of black rice to rice with brown rice and barley to increase the nutrients. The texture could be too much for babies to eat, so I boiled it with broth.
