1. Rinse the fresh beef venetian blinds, cut it into large pieces, then put it in a basin and soak it in boiling water for 3 minutes, stir it with a wooden stick constantly, and burn off the black skin on it for later bleaching. If it is convenient, you can scrape hard with a sharp object, which can also scrape off the black film.
2. Take out the scalded beef louver, drain the water, sprinkle some salt and white vinegar on the chopping block, then rub the black film on it and rinse it with water. Of course, you can also add a proper amount of salt, vinegar and corn flour and knead them together 15 minutes. Knead it twice, and the black film on it will be completely removed.
Just to remind you, the beef louver will be clean and beautiful after such cleaning, but it must not be washed as white as snow. White beef venetian blinds are first soaked in caustic soda water and then bleached with hydrogen peroxide. A catty of fresh beef louver can weigh up to three catties. I suggest you try not to buy it.
Except beef venetian blinds, squid and sea cucumber are generally treated in this way. Be careful when buying this kind of food.
2 How to fry beef venetian blinds won't get old? If you must make cold beef venetian blinds, the blanching time should not be too long. Generally, boiling water can be scalded for 30 seconds. The blanched beef venetian blinds must be soaked in cold water, which is also the key to crispy beef venetian blinds. Only in this way can the original and refreshing taste of beef venetian blinds be maintained to the greatest extent, and the freshest beef venetian blinds can be eaten. If you need a deep-fried belly, you must fry it quickly. Stir-fry twice, then turn off the heat. If the time is too long, the tripe will get old and affect the taste.
Can the Venetian beef be frozen? After the beef louver is cleaned, it is best to soak it in clear water, or wrap it in a fresh-keeping bag and put it in the refrigerator. Raw food can also be stored in the freezer of the refrigerator. It's no problem to put it in for a few more days. Take it out in advance when eating, and let it thaw naturally before burning. If it is cooked, it can be put in the freezer, but only for a day or two. If you put it in the freezer for a few more days, you should put it back in the oven before burning it. If you don't put it in the freezer, you can go back to the stove every two days to burn it. In this case, it tastes bad. You'd better buy it before eating it.
