Slice carrots as desired. I go small sliced for adding to soups, or you may want carrot sticks for adding to roasts.
Raw pack carrots, by tightly packing into canning jars, leaving 1/2-1 inch of headspace in each jars
Top half pint jars with 1/4 teaspoon salt, pint jars with 1/2 teaspoon of salt, or quart jars with 1 teaspoon of salt
Fill with water, leaving 1/2 inch of headspace
Wipe rims, making sure they are free from debris, and screw down lids and bands
Prepare pressure canner according to instructions, using cool water (most 16 quart canners need to be filled with 2 quarts of water, and the canning rack)
Arrange jars inside of canner, so that they are not touching. You should be able to fit 9 pints, or 7 quarts in a standard 16 quart canner
Lock lid on canner, leaving the steam valve open
Heat over medium-high heat until a steady stream of steam begins to escape
Let canner vent steam for 10 minutes
Close valve, and bring canner to 10 pounds of pressure (at sea level – see your altitude needs here)
Once canner reaches pressure, process jars for 30 minutes (pints), or 35 minutes (quarts)
Remove from heat and let canner return to zero pressure
Remove jars from canner only when safely cooled
After 24 hours, check for seal, and store in a cool place out of direct light.
