Notes

{Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.} Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middles of lids with finger.  If lids spring back, lids are not sealed and refrigeration is necessary.}
