I realize canned beets are not nearly as exciting as Pickled Beets, but I'm also optimistic that my offspring will enjoy smashed beets next year before they're in season. Since I plan to make most of our food for our baby, I figured beets were a good starting point.
Beets (amount is easily adjustable since all you need is boiling water)
Wash and drain beets. Cook beets, and submerge in cold water to peel. Slice, dice or leave beets whole.
Pack beets into hot jars, leaving 1-inch headspace. Ladle boiling water over beets, leaving 1-inch headspace. Adjust two-piece caps. Process pints 30 minutes or quarts 35 minutes in a steam-pressure canner at 10 lbs. pressure.
