How to make dry ice
Dry ice is made of carbon dioxide storage tanks and can be bought in some party stores and sporting goods stores. The size of the carbon dioxide storage tank depends on how much dry ice you need to make. Prepare a work area and prepare all the materials. You need to prepare load-bearing tape, cans and plastic ice packs. You also need to prepare some safety equipment. The plastic ice pack should be bigger to avoid flying away, or it will be a mess. Moreover, the high temperature resistance of plastic ice packs is also very important, and special bags are needed. If ordinary bags are not enough, gloves and goggles should also be worn, because dry ice is very cold, and even short-term contact may lead to frostbite. Put the carbon dioxide storage tank on the counter, then cover the plastic ice bag on the nozzle, seal it with tape, open the valve to release carbon dioxide, and fill the bag with carbon dioxide until it is full. Hold the packaging nozzle bag tightly, open the storage tank and release the pressure. If you are not ready, the bag may fly away. At first, we should release a small amount of carbon dioxide, and then gradually increase it when we are proficient. If it is not handled in time, unexpected things will happen. After the valve is closed, remove the adhesive tape from the bag, check whether there is dry ice in the bag, keep the bag upright, ensure that the valve is closed, and do not let children touch dry ice. Pour it into the jar so that it can be used. If the dry ice is used up, take it outside and throw it away. If it is kept indoors, low oxygen content will be very dangerous and should be disposed of in time.
How to cook dry ice smoked vegetables
The method of making dry ice smoked vegetables is very simple. You can put all kinds of vegetables in the pot and then pour dry ice into it. Dry ice will absorb heat and volatilize when it comes into contact with air, just like walking on clouds. It is a kind of solid carbon dioxide, which has no taste and color. It seems to be in a fairyland and will be used in the dishes of major restaurants. For example, lotus leaf yellow croaker surimi is often smoked into dry ice to scrape off the scales of yellow croaker. Then cut some flower knives in half, add custard powder, garlic powder, vegetable juice, cooking wine and salt for curing, add a proper amount of oil to the pot until it is 60% hot, then arrange the yellow croaker, fry it in the pot until it is crisp, take it out, put it in a round wooden box with lotus leaves, leave some base oil in the pot and add some cooking wine. After the monosodium glutamate, sugar and salt are mixed evenly, they can be poured on the fish. Dry ice is added to the wooden box and hot water is poured to create a smoking effect. Look at that.
