If you're, "stationary," as in already bugged out....

Get a stainless steel pressure cooker.
*NOT aluminum.
Bite the bullet and get stainless steel.

A pot of beans in 22 minutes....

A huge savings of energy/resource expenditure.

Great for rice as well....

And a whole bunch of things besides....

*IF you're doing.. or are going to be doing... large scale canning....

Get a LARGE All American. They are aluminum.
But that fact won't matter as you are canning.

A pressure cooker is the very best way to ensure safety.

Also substitutes as an autoclave for sterilizing surgical instruments.

And have that med kit and be ready to stitch something up if need be.
