Cooking potatoes have tips

Potatoes are home cooking and are popular vegetables that our people love. We can use it to make many dishes. What should we pay attention to when cooking potatoes?

1. When peeling a potato dish, only a thin layer should be cut off because the juice under the potato skin is rich in protein. If potatoes that have been peeled are not cooked immediately, they should be immersed in cool water to avoid darkening, but they should not be soaked for too long to prevent the loss of nutrients.

2. Potatoes should be simmered and boiled so that they can be cooked evenly. If the fire simmers, it will make the outer layer rotten and even crack, but it is raw;

3, long-serving potato surface often has blue-blue spots, when the side dish is not beautiful. If you put some vinegar in the boiled water (one tablespoon per kilogram of potatoes), the spots will disappear;

4, silty potatoes boiled on the rotten, even if the skin is hard to keep intact. If it is used for cold-mixing or diced potatoes, some salt water or vinegar of pickled vegetables can be added to the boiled potatoes, and the potatoes can be kept intact after cooking.

5, peeled potatoes should be stored in cold water, add a little vinegar to the water, can make potatoes do not change color;

6. Soak the new potatoes in the hot water and re-enter the cold water. It is easy to peel off the skin. Can be used for cooking.

Carbohydrazide CAS NO. 497-18-7

Carbohydrazide can act as an oxygen scavenger to prevent corrosion, especially in boiler feedwater systems, rocket propellant assemblies, color image and soap stabilizers, antioxidant rubber, boiler water deoxidizers and metal passivators. Carbohydrazide can also be used as an anticorrosive agent. Organic synthesis of intermediates.
