I’m fascinated by folks who can can. No, silly — not people who dance in spicy Parisian dance halls. I’m talking about folks who can can — jar, put up, preserve — fresh food for later. But I’m a bit fearful of preserving the fresh cucumbers that fill my crisper drawer. Do I know enough about food safety? What if my pickled treasures contaminate loved ones? Yikes! I need a mentor. Fortunately, help is around the corner with two upcoming “we can help you learn to preserve” events.
