Some of my (and other Celiac’s) favorites:
Elizabeth Barbone’s Easy Gluten- Free Baking
Plenty of options from Bette Hagman
Celiac Disease: A Hidden Epidemic by Peter Green and Rory Jones (I started reading this after my blood test was positive, but before my endoscopy)
Delight Gluten Free Magazine (dig this magazine, and my Mamasita was kind enough to renew it for TWO years for Christmas, THANKS!!)
(several already listed over in resources, to your right, check those out too)
Fabulous new Milwaukee focused Facebook page, thanks Kati!!!
