If you’re looking to pickle cucumbers and other veggies, be sure to grab a box of pickling salt. This salt has no additives (no anti-caking agents or iodine) which is exactly what you need for pickling. A giant box runs only a few dollars and will last you for a long time. Just keep it in an airtight container when canning season is over.
Pickling salt may sound hard to come by, but most grocery stores carry it. It may not be by the other salts, so just ask an associate to help you out. If you cannot find pickling salt, Kosher salt will also work.
