I picked up a small boneless leg of lamb roast at the grocery store today, mainly because I've never cooked lamb before. I'm a novice cook who is fine when it comes to following recipes but is trying to teach himself how to cook using techniques and flavours rather than numbers and ingredient lists. Anyway, long story short, I'm planning on roasting this cut of meat, but am not sure of the time. I was reading Alton Brown's "I'm Just Here for the Food" which was recommended to me and in the chapter on roasting he recommends for a good slow roast to roast the meat at 200F until it reaches 10 below the target temperature, and then removing the meat, covering it with foil, and cranking it up to 500 to finish. Now, Mr Brown says that when roasting, time doesn't matter and you should go by temperature, which sounds like sage advice to me, but I still would like to have an approximate idea of how long this will take so I don't shoot for a 6 o'clock dinner and end up going hungry till 9 or something. So can anyone estimate how long this will take to cook? The lamb leg is a small one, about a pound.
