It is of utmost importance that you use tested recipes from verified sources.  Be careful when surfing websites that provide home food preservation recipes as the recipes may not be safe.

The website provided by Jarden  Co. (Ball jar manufacturer) is a good site.  Also,  Ball Blue Books – published since 1996 are good.    http://www.freshpreserving.com/

 I recommend Extension Service sites.

 University of Georgia  is a great website for all things related to safe  home food preservation.  : http://www.uga.edu/nchfp    

The OSU Extension offers a  site as well:  http://extension.oregonstate.edu/fcd/foodsafety/foodpres.php

There is a toll-free “Hot-Line” for food preserving questions in Oregon: 1-800-354-7319    This is available throughout the summer
