Gluten (which comes from wheat, barley and rye) is in a lot of things you commonly use around the house ex. crackers, breads, cookies, cakes, soup packages, bisto gravy thickener, spices and a whole lot more.
I am cooking in a whole new way these days and it is rather difficult. I have some tried and true recipes that I usually cook, but I rarely experiment with new recipes, until lately so my husband doesn't get 'glutened' as they say.
note: this was a complete flop. my gas oven is not accurate, and always overheats. I have since purchased a breadmaker with a gluten free cycle and I bake Rob's bread in it.
