Pan-Grilled Flank Steak with Chermoula
While you can use touch to determine steak doneness (see "Keep in Touch," above), sight is also a useful tool. As steak passes from rare into medium rare, red juice beads begin to form on its surface. The juice flows more and turns pink as the steak heads toward medium. Steak cooked beyond medium releases brown juice. Chermoula is a versatile North African herb-and-spice sauce. Use a cast-iron grill pan for this dish, as a nonstick grill pan can't handle high heat.
