Cabbage
Wash cabbage carefully after cutting it in half, and let it boil for five minutes in well-salted boiling water; pour this water off and re-cover with fresh boiling water; let cook for half an hour, then add 1 teaspoon of salt, and let finish cooking, which will be in about another half an hour for a medium-sized cabbage.
Cabbage should never be covered while boiling, as covering increases the odour in cooking.
