Put the jars into a hot water bath. Make sure there is at least 1" of water covering the lids, and bring to a boil. Boil for 7-10 minutes (add 5 min for every 1000 feet above sea level you are). If boiled for less time, there is a greater risk that it won't seal or kill the bacteria, but your pickles will be crisper! Longer times will result in greater safety, but softer pickles. Again, pick your battles!
