1) Place the cabbage in a large bowl, sprinkle with the salt and rub in the salt with your fingers. Transfer to a colander and place the colander over the bowl. Fill a large sealable plastic bag with water, close tightly and place on top of the cabbage as a weight. Place in the refrigerator to drain for about 4 hours.
