Overripe cucumber pickles are a great way to use up big, seedy cucumbers that are past their prime for crisp dill pickles. This includes recipes that work especially well with mature cucumbers, like German Mustard Pickles or Russian Bear Claw Pickles, and most are traditional old fashioned recipes for using up the last of the harvest. Because cucumbers are low-acid, these recipes rely on tested vinegar brines and proper Water Bath Canning processing times for safe, shelf-stable jars.
