Spelt is an excellent high-gluten substitute for those allergic to wheat and it can be substituted for wheat in almost every recipe, including pasta. Spelt is easier to digest than most grains and is full of B vitamins, such as riboflavin, niacin, and thiamin, as well as iron and potassium. To prepare, pre-soak 1 cup spelt in 2.5 cups water several hours or overnight. Change the water, bring to boil and then simmer for 45-60 minutes until tender but chewy.
