Our kids, both boys and girls, love the cooking rotation. Who doesn't like to eat?! We often don't use the stove or oven. It's certainly not necessary to have one in the room if there's one in the building somewhere. In another church in which I did rotation model, we conducted our class in the "big kitchen." There are a number of cooking resources out there. In addition to the ones already mentioned, there's one called "Edible Bible Lessons" (or something close to that).
This book can be found listed in the Cooking Workshop BOOKSTORE.
