The ladies over at Creative Chicks post this yesterday. And since some of you might not follow them I thought I would share the information.
The University of Minnesota has put all of their Home Food Preservation Newsletters on-line. They can be found here. http://www1.extension.umn.edu/food-safety/home-food-preservation-newsletter/
Right now there are 5 newsletters to read through.... Even if your a seasoned vet when it comes to canning there might be something in here to learn! ;o)
