I've got a pork fillet (one of those long things), some real chicken stock, some brown basmati rice and some creme fraiche. How can I combine them to make something yummy? Was thinking maybe bung the sliced fillet, stock and rice with some onions into a casserole dish and bake, then stir creme fraiche through, like a big stroganoffy stew? Would that work or do I have to cook the rice separately?
