### STERILIZATION OF EMPTY JARS

        All  jams, jellies and pickled products  processed less

    than
    10 minutes  should be filled into sterile  empty  jars.

    To
    sterilize empty jars, put them right side up on 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  ft.

    At
     higher  elevations, boil 1 additional  minute  for  each

    additional
    1,000 ft. elevation.  Remove and drain  sterilize

    jars
     one  at  a time.  Save the hot  water  for  processing

    filled
     jars.   Fill jars with food, add lids   and  tighten

    screw
    bands.

        Empty jars used for vegetables, meats  and fruits to be

    processed
    in a pressure canner need not  be  pre-sterilized.

    It
     is  also unnecessary to pre-sterilize jars  for  fruits,

    tomatoes,
     and  pickled  or fermented  foods  that  will  be

    processed
    10 minutes or longer in a boiling-water canner.
