Go Dairy Free, by Alisa Marie Fleming is a fabulous book for anyone with dairy allergy or lactose intolerance. There are some great ideas and recipes for all tastes. I really like that there are options within the recipe to use one ingredient or the other. I made two recipes from this book this weekend -- cheesy quakers (crackers) and mac 'n cheese (both non-dairy of course). Both recipes require the use of nutritional yeast flakes, which have a sutle cheese flavor. Nutritional yeast flakes are vegan and completely dairy-free. I found a large container at a health foods store. My daughter loved the mac and cheese as well as the crackers. So happy!
