Pack peppers into hot, sterilized half-pint canning jars. Divide garlic between jars. Pour liquid over peppers in jars, leaving 1/2-inch headspace. Wipe jar rims; adjust lids. Process in a boiling-water canner for 5 minutes (start timing when water returns to boiling). Remove jars; cool on wire racks.
Because hot chile peppers, such as Hungarian wax peppers, contain volatile oils that can burn your skin and eyes, avoid direct contact with chiles as much as possible. When working with chile peppers, wear plastic or rubber gloves. If your bare hands do touch the chile peppers, wash your hands well with soap and water.
