Sugar and Spice Rub:
1 teaspoon salt
1 teaspoon freshly-cracked black pepper
1/2 teaspoon garlic
2 1/2 tablespoons granulated sugar
Combine ingredients in a small bowl. Rub one side of a 2 to 3 pound sirloin steak with half of the rub mixture. Let sit at room temperature for 1 hour.
Spread remaining rub mixture on the other side of the steak and let it sit at room temperature for at least 30 minutes. Cook over a medium hot grill for 5 minutes per side for medium rare. Do not cook over too hot a fire as the sugar will catch on fire.
