For those of us in the frozen states, pickling lime is hard to find this time of year. None was found in the grocery stores or hardware stores, or big box stores, as canning is a seasonal activity for those stores. I did find it in a farm supply store, where the canning section is there year round. Not the first time I have bought a brewing item at the farm store.
Still on the hunt for Magnesium Chloride. The local health store did not have it. Suggestions as to where to try?
Edit: searching around, I did find that pickling lime is also known as Kalkwasser.
