Sometimes I buy food in #10 cans, those big commercial size cans you occasionally see in the grocery store. But unless I was throwing a party there is no way I can eat all that food before it goes bad, so I can it!
From 1 can of pork & beans I canned up 7 pints and enough to go with dinner left over.
I heated up the beans first and I added some water to make sure they were not too dense in the jars. Then canned them according to the Ball Blue Book. I actually added some ham to mine so I canned for 75 minutes at 10 lbs pressure (low altitude). I'll need to drain some of the liquid off when I reheat to eat them, but I thought this was a pretty good deal for $2.68, much cheaper than buying 7 regular cans.
