• 2 teaspoons ground cumin
• 1 1/2 teaspoons kosher salt

How to Make It

Step 1
Stir together brown sugar, chile powder, cumin, salt, garlic powder, and cayenne in a small bowl. Rub all over brisket, and chill at least 1 hour or up to overnight.

Step 2
Stir together broth, vinegar, Worcestershire sauce, and 1 cup of the ketchup in a bowl. Place brisket in a 5-quart slow cooker; pour broth mixture over brisket. Cover and cook on LOW until very tender, about 8 hours.

Step 3
