Prepare the pressure canner and jars. Add a few inches (8 cm) of water to the pressure canner, depending on the instructions from the manufacturer, and allow it to heat up to 180 degrees Fahrenheit (82 degrees Celsius) on the stovetop.
Combine all of the ingredients (except flour, sour cream, and beef broth) in a large bowl. Mix well.
Fill one jar at a time, adding all the ingredients until the jars are full. If you have any room remaining, you can top off the jars with hot beef broth.
Make sure you leave an inch (2.5 cm) of headspace.
Remove the air bubbles, double-checking for headspace.
Wipe the rims of the jars to get rid of any food particles. Then, apply the lids and bands until they are fingertip tight.
Place the jars in a pressure canner that has two inches of simmering water. Put the lid on the canner and adjust it to the locked position.
Turn the heat on the stove to medium-high, then vent steam for 10 minutes.
Put the counterweight or weighted gauge on the vent. Bring the pressure to 10 lbs for a weighted gauge canner or 11 lbs for a dial gauge canner. Process the jars for 90 minutes for quarts or 75 minutes for pints.
When the jars have finished processing, turn off the heat, then allow the canner to come back down to zero pressure.
After five minutes, remove the lid, then let the jars cool for 10 minutes before you remove them from the canner.
Let them cool for another 24 hours at room temperature, then check the seals, label the jars, and store them for up to one year.
