I've made several of these, with various techniques. This past cook I reverse seared it.
I got the (prime) cut from Costco, around $6.50/lb. I used Stubbs briquets & a few chunks of Red Oak. Seasoned only with Suzie Q's. I'm guessing the massive marbling is what made this one of my best tri-tips ever.
I also made homemade chimichurri sauce; Olive oil, fresh garlic, Italian parsley, red wine vinegar, ground oregano, red pepper flakes, salt & pepper.
Sliced the tri-tip thin & made sandwiches on fresh local bread.
