0 1 dried shrimps must be fresh, preferably fresh shrimps that have just been fished out. Take them home, clean them, remove those impurities, and remove the excess shrimp.
Boil water in the pot, with a little salt, or without it. It's up to you. Put the shrimp in and turn it quickly with a colander.
Don't let the shrimp stay in the water for too long. Take it out and control the moisture immediately after it changes color slightly, and spread the shrimp evenly to dry.
If there is a dryer, just put the shrimps in and dry them. If there is no dryer, it usually takes a day to spread shrimps on some grids and then expose them to the sun. Put them away.
