• Let the tri tip sit out at room temperature at least 20 minutes before grilling.
• Mix rub ingredients together in a small bowl.
• Use a pair of clean rubber or plastic gloves to rub the tri tip with olive oil, covering it completely. Then rub the spices evenly over the meat.
• Grill over medium heat for 10 minutes on each side with direct heat. Continue to grill another 30 minutes with indirect heat. Use a meat thermometer to determine when the steak is cooked to your preference. For a medium cooked trip tip steak, the center temperature should reach 155 degrees.
• When there is about 15 minutes left, baste the tri-tip with half of the homemade bbq sauce- recipe below.
• Let the meat sit for at least 5 minutes after removing from the grill before cutting into it. Cut into thin slices and serve with the remaining bbq sauce for dipping.

For The Homemade BBQ Sauce:

• Warm the vegetable oil in a medium saucepan over medium-high heat. Add the garlic and cook for 1 minute or until the garlic turns golden.
• Add the remaining sauce ingredients, including Tabasco sauce to taste, and bring to a boil. Reduce heat and simmer about 15 minutes.
• Divide the sauce in half (you will use half to baste the tri tip and the other half for dipping).
