Notes
Note: general water bath canning instructions can be found here: Water Bath Canning.Store your jars in a cool dark place and wait at least 3 weeks before sampling. Though these will keep longer, it is a good idea to try and use up your canned goods within a year. If any of the lids didn't seal, you can reprocess or just store them in the fridge and eat them as a quick pickle.
