Price of Great Value pintos beans per 15.5 oz can: 86¢.
Price of 4 pounds of dried pinto beans: $3.76.
Number of pint jars worth of beans you get from a 4 lb bag: 15.
That brings us to 25¢ per jar because I’m reusing lids. I’ll test each jar tomorrow for a proper seal to see if any of the reused lids failed. But they almost never do.
If you have to buy lids or don’t have Tattler reusable kids then it’s going to cost 55¢ per can and after figuring in labor and electricity it’s probably not worth it. But if you are paying ~$1.40 a can for name brand pintos in a can then it’s still worth it.
This will become burritos, refried beans and other things in the future.
The blades don’t seal then they aren’t indented and the lid can easily be removed. There are two parts to a canning lid. There’s a disc lid with a rubber seal and then there’s a ring that tightens it down. The lid part is slightly bowed and when it seals it will turn convex into concave. That let you know everything’s good. But even brand new lids can fail. Typical instructions are to put unsealed jars in the fridge and use them right away or to reprocess to seal again.
They do have a finite life. The rubber can be all distorted so that it won’t seal properly or you bend lid trying to get it off.
Thanks!
I was once helping a friend clean and he had a jar of ??? that was totally full, but had a popped lid. He wouldn’t take it on trust that the lid pop was a designed feature meaning he should toss the product. I insisted and he ended up looking it up.
