Its firm flesh and assertive taste make arctic char a great choice for the grill. The ground chipotle in the quick marinade gives the fish a hint of smoky heat.
Cooks' note:
·If you can't grill outdoors, fish can be broiled, skin side down, without turning, on oiled rack of a broiler pan 5 to 6 inches from preheated broiler, about 6 minutes total. (Skin cannot be crisped in broiler.)
·You can substitute 2 (1-lb) pieces of salmon fillet (about 1 1/2 inches thick) for the arctic char. Grill, turning over once, about 12 minutes total.
