I have found that waffles are somewhat difficult to make gluten-free, as the texture must be right for the waffles to hold their shape and release from the waffle iron. I tried a new recipe today that I found here at the Canada Bed & Breakfast Hosts website. I substituted gluten-free ricemilk to make it dairy-free, and I used canola oil and organic shortening (refined palm oil) to make it soy-free and trans-fat free.
There is also a recipe on the same page for gluten-free biscuits. I'll have to try that sometime.
They have more recipes at www.canadabbhosts.com/recipes.htm, including more gluten-free recipes (but not necessarily soy-free or dairy-free).
