Canning method
Wash and rinse half-pint canning jars; keep hot until ready to use. Prepare lids according to the manufacturer’s directions.
Wash, peel and thinly julienne the jicama and chayote, discarding the chayote seed. A mandoline slicer works well.
In an 8-quart Dutch oven or stockpot, combine all ingredients except the chayote. Bring to a boil and boil for 5 minutes. Reduce the heat to a simmer and add the chayote. Return to a boil, then turn off the heat.
Fill clean, hot half-pint jars with the hot solids, leaving 1/2-inch headspace. Cover with boiling-hot cooking liquid, maintaining 1/2-inch headspace. Remove air bubbles, adjust headspace if needed, wipe jar rims with a damp clean paper towel, and apply two-piece canning lids.
Process half-pint jars in a boiling-water canner for 15 minutes at 0–1,000 feet, 20 minutes at 1,001–6,000 feet, or 25 minutes above 6,000 feet. Cool undisturbed for 12–24 hours, then check seals.
