To my mind there's no point barbecuing food by starting or finishing it off in the oven - you need the smokiness, the marinade, the herbs etc Also much better to serve meats that can be served rare or medium rare i.e. beef or lamb (even pork can be left so a bit pink in the middle). We had some fabulous 1 and a half inch thick sirloin steak yesterday, served very rare - it was so tender and utterly delicious.
Well I've bought a sleeve of fillet mignon which I'll slice as I need and then done on like lubricated pan with onions and mushrooms - that meat is too good to barbecue.
PS - I'm only procrastinating here - to get round to get housework done. Have done the kitchen window and kitchen door. Just a wee rest now.
