Step 1

Combine all seasoning ingredients in a bowl and mix together.

Step 2

Generously sprinkle the steak all over on both sides with the coffee spice rub and gently massage it in. Let steak stand at room temperature for 30 minutes.

Step 3

Meanwhile, prepare a grill for direct cooking over high heat.

Step 4

Cook steak directly over the flame, flipping halfway through cooking, until well browned. This is about 3-5 minutes per side to cook a thin flank or skirt steak medium-rare. Adjust cooking time accordingly depending on the thickness of your steak and desired doneness.

Step 5

Transfer steak to a cutting board and let rest for at least 5 minutes. Slice the steak across the grain and serve.
