Can I use the leftover pickling brine? I have some leftover brine that was leftover from making canned pickles, it was heated up to put in the canned pickles to make them. Can I use this brine again to make more canned pickles? The brine never touched the pickles or anything else.
Not sure any of the above have read your question completely.  You are asking; can you store extra brine that you made but was not used in your pickling process.  I do this systematically when my  Green Beans are going crazy.  I mix up extra brine and store it in the refrigerator for up to 2 weeks.  The brine is simple pickling salt, water and white vinegar.  Then I can use it incrementally as my produce comes in. Saves me a few steps by simply reheating premixed brine instead of making it each time.  I like this approach because it allows me to put up a few pints at a time while the beans are fresh.  Have never had a problem with my Dilly Beans.
