Have all the abalone on the hotel table been washed clean? How to clean abalone?

2. Soak the dried abalone in cold water for a few minutes, and then brush the dirt off the surface with a clean toothbrush. Soak the cleaned abalone in hot water at 40-60℃ for 4-6 hours, then take it out and heat it in a cold water pot. At the same time, add a small amount of borax (about 20 grams of borax for 500 grams of abalone) and cook for 2 hours. Away from the fire, abalone is still in the pot. Change the water the next day, cook for 1 ~ 2 hours, take it out after cooling, rinse borax with clear water and cook it.
