Celiac and GF
Keep it simple. The less ingredients, the easier it is to cook GF.

There are definitely a few nuances with flour substitutions, but nothing that can't be learned. You'll just have to find the one that suits your taste and texture preferences. Shopping used to be quite a pain, but most large grocery stores now have some type of gluten free section. If your's doesn't, try a health food/organic grocery/market (Whole Foods). If that doesn't work, there are many web sites that do mail order.
