Fruits and veggies will process at different times depending on the altitude.

As altitude increases, water boils at a lower temperature. The timings listed are for altitudes up to 1,000 feet. (If you don't know your altitude, call your county extension office.) For higher altitudes, make the following changes:

Boiling-water canning: Use a longer processing time. Call your county extension office for detailed instructions.

Jellies and jams: Add one minute to the processing time for each additional 1,000 feet of altitude.

Pickles and relishes: Processing times vary; call your county extension office for detailed instructions.

Pressure canning: Times remain the same, but different pressures must be used. Call your county extension office for detailed instructions.

Sterilizing jars: Boil one additional minute for each additional 1,000 feet.

Pie fillings: At higher altitudes use these processing times for quarts (in minutes):
