Prepare a smoker with wood or pellets (preferably hickory or apple wood) to 225℉/107℃.
In a mixing bowl, combine salt, sugar, crushed black pepper, cajun powder, garlic powder, onion powder, cumin seeds, paprika powder, and crushed chili powder. Use a whisk to blend thoroughly. Store in a cool, dry place for future use.
Use a knife to trim excess fat from the beef, spread olive oil evenly over beef, sprinkle marinade powder evenly over the surface of the brisket.
To ensure accuracy, insert the Typhur Sync Gold wireless probe into the thickest part of the meat, making sure the safety line is completely immersed.
Select beef→ roast→ Tri Tip in the parameters list. Set the target temperature to 135℉/57℃.
Transfer the tri tip into your preheated smoker, then securely close the lid.
To begin the process, simply press the start button on your phone.
Carefully remove the tri tip and place it on a heat resistant surface. Let it rest for at least 10 minutes.
