I think I'm in love . . . with oven canning! Just pack the jars with anything that is dry, no liquid. Heat for one hour in a 200 degree oven. Put the lids on when you take the jars out of the oven and they seal by themselves.
I canned saltine crackers, club crackers, graham crackers, powdered milk, cornmeal, and flour today. Cereal, baking powder, and baking soda next. Yeast powder can not be canned.
The food doesn't get stale on the shelf and no freezer burn. You can store the jars anywhere, since there is no liquid that will freeze.
