However, salt has been used for generations as a preservative. And this Fall, as I struggle to store a year’s worth of food, preservation has an entirely new meaning in my life.
Pickling and canning are a mainstay of preserving foods, but they require an acid — usually vinegar. I have no vinegar. I have no lemon juice. I did discover that rhubarb juice is almost as acidic as white vinegar (with a pH somewhere between 3.0 and 4.0). So I tried making sweet pickles with a brine of rhubarb juice, birch syrup and ground celery leaves. No salt.
I was pretty pleased with the taste and quite proud of myself for finding a way to pickle without vinegar or salt. I put my 4 jars of experimental pickles in the pantry. Then, while researching more thoroughly, I discovered caution after caution about pickling or canning with homemade vinegars.
Apparently, with the variable pH of homemade vinegars, they can’t be relied upon to prevent botulism. Great. I imagine the headline: Family of Retired Physician Eating Local Dies of Botulism! I immediately moved my 4 jars of sweet pickles from the pantry to the fridge and put them on the ‘to be eaten soon’ list.
So — rhubarb juice pickling is out.
