@Uzi2 is a wise man. Some great comments above. I am a huge fan of pressure canned chuck roast. Buy the cheapest ugliest meat you can find. Pressure canning turns it into mouth watering, fall apart on your plate cuts of meat. Million things you can do with it. I have about 30 pounds or so canned right now.
I can chicken but it is thighs and drumbsticks for the dog. Agree with Uzi here as well that frozen gives you more options. Now, if prepare a huge load of chicken soup; well that is a different story. The stuff for the dog is fine though. Actually smells like canned tuna
Good job on the potatoes. I can potatoes, usually 10 pounds at a time. They are one of those things that are just better when canned. Instant mashed potatoes, fries, baked, or thrown into a soup. I have found that I prefer to keep the chunks on the larger side so they don't get mushy on me. Then I cut them to size, depending what I am using it for. I start off by pouring about a half inch of water in the jar, then fill with potatoes, given it a shake as I go so the potatoes settle better. Once I am about an inch from the top with potatoes I fill it with water to a one inch head space.
Almost everything I pack now gets a half inch of water in the jar first. I found that it helps eliminate those little air pockets that can screw up your seal/headspace. Yes, I use a plastic thingy to get out the air, but starting with a bit of water guarantees no issues.
I can one to two times per week. My biggest issue right now is finding lids. They are becoming available but the prices are stupid high. I have actually started to test used lids. So far I have had no issues. Figured I better see if it works, just in case.
