Peel and cut rhubarb in one-inch pieces. Put in a saucepan, sprinkle generously with sugar, and add enough water to prevent rhubarb from burning. Rhubarb contains such a large percentage of water that but little additional water is needed. Cook until soft. If rhubarb is covered with boiling water, allowed to stand five minutes, then drained and cooked, less sugar will be required. Rhubarb is sometimes baked in an earthen pudding-dish. If baked slowly for a long time it has a rich red color.
