Preserved Quinces

Wash, peel, quarter, and core the quinces before measuring them. Put them into a cooker-pail, add the water, and when they are boiling hard, put them into a cooker for ten hours or more. If not perfectly tender, heat them again to the boiling point and set them in the cooker for as many more hours as they require, depending upon their ripeness. Thoroughly ripe quinces will probably not require this second period of cooking. Add the sugar, bring them to a boil, and set them in the cooker for four hours or more. If they are not rich enough, boil them slowly, uncovered, until they are of the desired consistency. Long, slow boiling is what gives quinces the red colour so much admired.
