OOHHHHHHHHHH!!!!!!!!
Good deal....I've had good rack of lamb but I usually can't get by the smell of domestic sheep cooking
Get a good peppercorn sauce and do it just like a beef roast.
Make sure you use a meat thermometer and pull it out of the oven at 148 to 150 degrees.....then let it rest on the counter. If you over cook it it really ruins it for me but if you catch it right it is awesome!!!!!
Enjoy it man....I've never had big horn but if it's anything like dall you won't be sharing it with anyone!!
