Query: idiot's guide to living with lactose intolerance

This is the silliest cookbook I have EVER read. Sheri Updike doesn't offer interesting new takes on the foods we all love; she substitutes lactose-free milk and margarine for regular milk and butter and claims to have created new recipes. She offers a "recipe" for Jiffy cornbread mix, using lactose-free milk and margarine! I could have done that when I was in middle school, but I was too busy baking dairy-free cornbread from scratch! And did I mention that Updike's writing is awful? For example, "According to personal taste, as the eggs cook the whites will become opaque and the yolks will harden." Actually, I'm pretty certain that regardless of my "personal taste," the eggs will cook as above--that's basic science--which, like basic writing, Updike apparently missed. Avoid this book!
