Cut 5 pounds rhubarb fine. Then pour on 1 gallon boiling water and let stand 3 or 4 days. Strain. Add 3 1/2 pounds brown sugar, 5 oranges, 5 lemons and 1 cup raisins or more. Let stand 3 or 4 days. Then strain through a cloth, let stand as long as it works. Don't put cork on tight until a few months after it has stopped working, then it can be bottled.
