Last weekend I did a tri-tip roast for the first time. It turned out very good. First I seared it at 550° F for 90 seconds on each side. I just used salt and pepper for seasoning.
Then I took it out of the grill and shut the grill down until it reached 350° F and then cooked it inderect until it reached a internal temperature of 140° F.
Then sliced and served
