Grandma's Recipes #10 - Beans!

There are two identical canned bean recipes in Grandma's little tin with very different handwriting.  Neither recipe specifies what type of bean, and I don't know what kind she grew in her garden.  I think this recipe is for green or yellow beans, and doing a little googling seems to confirm that others have used vinegar and salt to can those varieties.  Grandma moved off the farm when I was six, so I don't have a lot of memories of it.  Most of the garden memories I do have revolve around heaping bowls of snap peas that we'd eat while watching Days of Our Lives and shooting Stefano and John Black with a suction cup gun (something like this, but covered in the slobber of 7 grandchildren who were all convinced that licking the suction cups made them stick to the TV better).   I've never canned, but given how prolific my green bean plants were this year and how much tater tot casserole my husband can eat, this is one I may need to try.

Beans

Boil this for 7 minutes.  Pack beans in a jar and add the brine.
