To make the sauce: In a small heavy-bottom saucepan, whisk the sauce ingredients with 1/2 cup of water. Bring to a simmer over medium-high heat, then reduce the heat and simmer for 10 minutes, stirring occasionally.

2

Trim most of the exterior fat from the steaks. Allow to stand at room temperature 20 to 30 minutes before grilling.

3

Roughly chop the garlic, and then sprinkle the salt on top. Using both the sharp edge and the flat side of the knife blade, crush the garlic and salt together to create a paste. In a small bowl, mix the garlic paste with the oil, rosemary, and pepper. Smear the mixture evenly all over the steaks.

4

Grill over Direct High heat until cooked to desired doneness, 6 to 8 minutes for medium-rare, turning once [if flare-ups occur, move the steaks temporarily over Indirect High heat]. Remove from the grill and let rest for 3 to 5 minutes. Serve warm with the sauce on the side.
