Ingredients

  • Sauce
  • 1/2 cup ketchup
  • 2 tablespoons white wine vinegar
  • 1 tablespoon Worcestershire sauce
  • 2 teaspoons molasses
  • 1 teaspoon soy sauce
  • 1/2 teaspoon chili powder
  • 1/2 teaspoon granulated garlic
  • 1/4 teaspoon celery salt
  • 1/4 teaspoon liquid smoke
  • Rub
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon celery salt
  • 1/4 teaspoon fresh ground black pepper
  • 1/4 teaspoon granulated garlic
  • Meat
  • 1 (2 lb) tri-tip roast, about 1 1/2 inches thick
  • 2 tablespoons extra virgin olive oil

Method

  • Make the sauce: in a medium saucepan combine the sauce ingredients with 2 tablespoons water; bring to a simmer over medium heat; cook for about 1 minute, stirring occasionally; set aside half of the sauce for dipping.
  • Make the rub: in a small bowl, mix the rub ingredients very well, use your fingertips (works better).
  • Let the roast stand at room temperature 20-30 minutes before grilling.
  • Lightly coat the meat with the oil and season with the rub, pressing spices into the meat.
  • Grill over Direct Medium heat until well marked on both sides, about 10 minutes, turning once.
  • Move the roast over Indirect Medium heat and cook to desired doneness, 20-30 minutes more for medium-rare, brushing the meat with the remaining half of the sauce on both sides and turning it over every 5 minutes or so.
  • Remove from the grill and let rest 5-10 minutes.
  • Cut meat across the grain into very thin slices.
  • Serve warm with the dipping sauce.
