Use perfectly fresh, crisp rhubarb, peel and cut in small pieces as for pies, fill a Mason jar with the fruit and pour over it freshly drawn water. Screw on the top and by the next morning the water will have settled in the jar. Fill the jars full with fresh water, seal again and the fruit is ready for winter's use. In making pies it takes less sugar than the fresh fruit. Or, boil the rhubarb a few moments, as for sauce, with or without sugar and put into jars while it is very hot just as other fruit is canned.
