Purchased a Costco membership this past weekend. Nothing like bulk shopping to put you in touch with your own mortality. You think to yourself "hmm, I wonder if I'll finish this 55 gallon drum of anchovy paste before I die".
Anyway, bought a 6 lb boneless rib roast. Rubbed it with s&p, ground coriander and mustard seeds, and seared it on the grill. Finished it with indirect heat. Came out freakin perfect.
