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 founded 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.
In a large, heavy saucepan, heat oil and sherry or water until bubbling. Add onion and sauté 5 minutes, stirring frequently to prevent browning.(If mixture appears dry, add 1 to 2 tablespoons water.) Add carrot, celery, bay leaf, potatoes and stock. Cover pan, bring to a boil and cook over medium heat 10 to 15 minutes, or until potato is tender. Add milk and corn and simmer 3 minutes, or until corn is tender.
Discard bay leaf. Puree 1 cup soup in a blender, then return to the pot. Season with cayenne. If desired, garnish with a dollop of nonfat yogurt. Serves 4.
