You all are in luck because I seen her make this cranberry juice and asked.her questions.
For 1 quart jar she rinsed 1 cup of whole cranberries in hot water and added to the sterile quart jar. She then added 1/4 cup of white sugar and poured hot spring water over top of the cranberries and sugar in the jar, leaving head space. She then capped the jars and water bathed them. When they came out of the water bather, she told me they have to sit at least two weeks, then they will be ready.
