I just bought a long wanted clay baker. I have two questions: 1. One of the recipes calls for a "aubergine". Anyone know what this is? 2. Has anyone out there ever cooked a prime rib or any other cut of roast in a clay baker? I need to know times per pound and any other hints as I would like to cook a prime rib for my Dad on Father's Day. Thanks, Gayle -- "Etiam sciurus caecus quasdam nuces invenit"
