In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease. In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore!, and I am the co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.
Sift the dry ingredients & mix them thoroughly. Cut in the butter & shortening. Mix in buttermilk as gently as possible. Dough should be moist & slightly sticky so add more if necessary, a little at a time.
Roll out about ¾ inch thick between sheets of plastic wrap or waxed paper. Chill until solid enough to cut. Preheat oven to 425 degrees. Cut with a floured cutter. Brush tops with cream if desired for a golden color. Bake 12-15 minutes for small cutter, longer if larger cutters used. The biscuits should be very light brown on bottoms, light golden on top (if wash is used). Do not over bake or they will be dry.
