Recently had the desire to make small quantity of pickled beets when I saw the beets at the local produce market. I only bought about 1.5 to 2 lbs, so it's not a very large quantity. when I started looking for recipes, almost all were canning recipes. For this small quantity, which we'll use up within a couple of weeks, do I need to go through the canning process? Will they really 'pickle' properly if I don't?
