My son's going back down to UC Santa Cruz this weekend and wanted some tri-tip before he left. Got some USDA prime from Costco. They sometimes have it for less, but 8.99 isn't too bad for prime. Dry brined overnight, then seasoned with black pepper, garlic, and light touch of chili powder. Into the Memphis at 190F along with mac and cheese. Smoked until IT 127. Seared on the gasser.
