I was doing a craft fair and this woman said she was at a show where the consultant made a cake in the microwave in a micro rice cooker. It had the frosting melted at the bottom like the one you make in the fluted pan. Then she served the cake in dishes and cooked hamburger meat in the rice cooker. Has anyone ever done either of these things? What are the times? What do you use the burger for after it's cooked, a taco ring or do you make a burger and rice dish? Thanks.
