Sterilize the number of pint jars that your pressure canner will hold.
Begin boiling water to fill jars- I use an electric teapot for this job.
Add 1/2 C dried pinto bars to each pint jar.
Add salt and chili powder to each jar on top of the beans.
Fill each jar with boiling water to 1" head space.
Stir with nonmetallic spatula to mix ingredients and remove air pockets.
Wipe tops of jars with damp cloth and add new clean lids and rings.
At this point, let the beans rehydrate for an hour or so before adding them to the pressure canner.
Fill your pressure canner with water as directed according to manufacturer's directions, and add jars on top of rack inside the canner.
Process pints for 75 minutes at 10 lbs. pressure in pressure canner.
Make sure to let canner cool naturally before removing jars to prevent syphoning of liquid.
Check lids to make sure they have sealed...without pushing down on them. If they don't seal, use immediately or refrigerate and use within a few days.
Set in a draft free area for 24 hours before moving.
Make sure that all lids are indented (without helping with that) and label/date lids before adding to your pantry.
NOTE: A 2 lb bag of beans will fill 9 pints with 1/2 C in each pint with a little extra. My for pressure canner holds 9 pints. I simply added about 1 T extra in each to finish the bag...but, that reduced the liquid in each pint after processing. Many canners prefer more liquid in each canned jar. ALSO, I can't imagine soaking these longer than an hour since they were very soft when opened. Soaking longer might produce really mushy beans. If you want to have more liquid in the finished jars, keep the amount of dry beans added at 1/2 C.
