Greens, Savoys, and Cabbages must be boiled in plenty of water, with a tablespoonful of salt to every half-gallon. They must be kept well stirred down, and if boiled with the lid off will want no soda to keep them green, unless the water is very hard. The time required to cook them depends upon their age. The stalk should be split up, so that it gets done as soon as the green part.
