大闸蟹怎么洗才干净

To clean freshwater crabs (such as Chinese mitten crabs), you can follow these steps:

1. Fill a large bowl or basin with water.
2. Add some salt to the water (about 1 tablespoon per liter) and mix well.
3. Place the crabs in the saltwater solution and let them soak for about 15-20 minutes. This will help to remove any dirt or impurities from the crabs.
4. Use a brush or a soft sponge to gently scrub the crabs, paying special attention to the legs and joints where dirt tends to accumulate.
5. Rinse the crabs thoroughly under running water to remove any remaining salt or debris.
6. Your crabs are now clean and ready to be cooked!

Remember to always handle live crabs carefully and humanely when cleaning them.
