A friend of ours just moved into his first apartment. He's a young, single guy who wants to learn to cook but doesn't know much now. We want to get him the deep covered baker, but his microwave doesn't have the carousel in it. I thought there were instructions for microwaves without them, but I can't find anything. I have never had one without it. Any tips or suggestions? I'm assuming he will have to turn it, but how often? Thanks!Di
