Does anyone know of a good website (or book) to find information for canning?

Thanks much for the online info, including the University of Georgia link. They actually have online classes you can take about canning/preserving food at home. Just starting now, but looking forward to learning more. Thanks, everyone!

I love Well Preserved, great reco!

Thanks to everyone! I can't wait to track down some of these books so I can get canning.

Check out www.savingtheseason.com/ I've taken canning classes with Kevin and he's so enthusiastic about preserving and sharing his knowledge. If you're in the Los Angeles area, he's a great resource. His website includes recipes and info on how to safely put up your produce.

Try the hashtags #tigresscanjam or #canvolution on Twitter to find some great blogs with lots of canning recipes.

My two favorite resources for excellent (often somewhat unusual) canning recipes are both by Brits. The first, which happens also to be full of garden-related eye candy, is by Nora Carey, and is called "Perfect Preserves: Provisions from the Kitchen Garden" (1990, distributed in the U.S. by Workman Pub.). The other, "Sensational Preserves," by Hilaire Walden, was published by Conran Octopus in 1995 and then again in 2000. I don't know if either is still in print, but if not, you can probably find them at alibris.com, which is my go-to site for used and out-of-print books. Both books are full of useful information about making preserves that one doesn’t see any more in books by US authors. (Some of their tips can be found in my 1943 edition of “The Joy of Cooking.”) Although these books do not provide any specific answers though to the ratio question you pose, they are excellent and even inspiring resources. ;o)

Well Preserved by Eugenia Bone is a great book.
