My Way: 1 cup DRY beans (you do not need to precook), fill the rest of the jar with water and inch from the top. Process at 15 lbs (my altitude) pressure for 50-60 minutes NOT 90 minutes like the USDA recommends. Using old baby blankets helps make clean up a cinch. Put a little bit of vinegar in the canner to help with hard water staining of jars. Make sure to borrow your friends canner that does 14 quarts at once. It will make your canning day go a WHOLE lot quicker.
