Made tri tip last night. Followed recipe for Santa Maria tri tip. Sear, rest, then roast, basting with an oil and vinegar mix while roasting. During the roasting I got a lot of smoke, I believe from the basting mix dripping on the coals. The smoke flavor was very strong and not a pleasant smoke flavor either. Is the only solution to use a stone/drip pan during roasting? I get a little of this with the T-Rex steak cook also. Any suggestions?
