What is the coup of "making sea cucumber by water"?
Sea cucumber is a nourishing food with rich nutrition. Soaking sea cucumber is the key to eating. Whether the soaking method is appropriate or not directly affects the yield, quality and taste of sea cucumber. The principle of water-soaked sea cucumber is "soak more and cook less".
Methods: First, dry sea cucumber was washed, boiled in a cold water pot for 10 ~ 20 minutes, fished out and put in the pot, and soaked in boiling water for 7 ~ 8 hours. If your hair is not cooked thoroughly and your hands are hard, you can put it in boiling water 10 minutes and continue to soak for several hours. Sometimes it needs to be boiled repeatedly, but it can't be cooked for a long time. Only by soaking more sea cucumbers and cooking less can they absorb water and swell gradually. If the sea cucumber is fully developed, it can be cut along the longitudinal direction of the first training to remove impurities such as fascia and mouth in the abdominal cavity, and then washed with clear water. Large sea cucumbers can be cut into 2-3 sections horizontally, then cut one by one vertically, and finally made into dishes.
When sending sea cucumbers in water, we should also pay attention to: first, avoid oil, so as not to hinder the sea cucumbers from absorbing water and swelling; Second, avoid salt, so as not to be difficult to pass; Third, avoid freezing, and the prepared sea cucumber can be stored in the refrigerator for a short time. Put it in the freezer, otherwise the sea cucumber soap will be honeycomb-shaped, the elasticity will be reduced, and the taste will be very slag. When you cry in summer, you should pay attention to changing the water frequently to prevent the sea cucumber from deteriorating.
When buying sea cucumbers on the market, it is best to choose the ones with large body, thick meat and no sediment. Some vendors add a lot of lye when brewing sea cucumbers. When it is found that the sea cucumber is over-inflated, the meat loses its toughness, and even cracks and breaks with a little pinch of your fingers, and you can smell obvious alkaline taste, then this kind of sea cucumber has low nutritional value and is not good for your health. It is best not to buy it. (Pu Zhaohe, Chengdu University of Traditional Chinese Medicine, Sichuan: 6 10075)
