Never buy store bought again!! Making it is super easy and there is no need to worry about if it is safe for preserving. Actually, pickling spice has nothing to do with the actual pickling process, rather its sole job is to add the spice and flavor to your pickling brine.
So instead of letting some company determine what flavor that your pickles will absorb, make your own and rest assured that the flavor is one that both you and your family will enjoy.
