- Trim any excessive fat from the brisket, leaving about ¼ to ½ inch on the surface for moisture and flavor. As you are trimming, put the fat into a small pot, we will boil this down to make tallow for our secret weapon later.
- Season the brisket generously with coarse kosher salt, coarsely ground black pepper, garlic powder, and onion powder. I like to mix it all into a shaker first so I can apply it more evenly. About 3 parts pepper, to 1 part salt, then a smaller amount of garlic and onion powders. Apply the seasoning evenly, ensuring good coverage on all sides.
- For a better bark formation, you can use a thin layer of mustard as a binder before applying the seasoning. This step is optional but can enhance the flavors.
