Cut salmon into bite-sized pieces, leaving some bones for flavor (soften during canning).
Chop potatoes, carrots, and onions.
Combine all ingredients in a large pan and cover with hot water, broth, or wine. Boil for five minutes to blend flavors.
Add salt, herbs, and spices to taste (flavors intensify during canning).
Fill hot, clean canning jars with soup mixture, leaving one inch of headspace.
Wipe rims clean, add water to the pressure canner, and heat.
Vent steam for 10 minutes, then add weight.
Process pints for 100 minutes at 11 lbs pressure in a dial gauge canner or 10 lbs in a weighted gauge canner. Restart timer if pressure drops during processing.
Turn off heat after processing, and let the canner depressurize naturally.
Wait for zero pressure, then remove lids and jars.
Cool jars at room temperature for 24 hours, check seals, label, and store in a cool, dark place.
