We often tell people to save the brine from their pickle jars. It's a magic elixir, full of flavor and great for salad dressings, cocktails and as the secret ingredient in sauces and soups. But the easiest way to recycle good pickle brine is to make new pickles.
In this case we went from cucumbers to zucchini and used our vacuum sealer to speed up the pickling process. If you don't have a vacuum sealer, just submerge your vegetables in the brine for several days until they are pickled to your satisfaction.
