the rack in a boiling-water canner. Fill the canner and
jars with hot (not boiling) water to 1 inch above the tops
of the jars. Boil 10 minutes at altitudes of less than
1,000 feet. At higher elevations, boil 1 additional minute
for each additional 1,000 feet elevation. Remove and drain
hot sterilized jars one at a time as filled.
