During Passover, Sydney and I have had numerous requests for gluten free croissants. We have created recipes for our gluten free clients, friends, and family members. I must admit the individuals who are gluten free seem to grow each year. My nephew was born with Celiac disease. Celiac disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients from food. People who have celiac disease cannot tolerate gluten, a protein in wheat, rye, and barley.
