Cooks' Note
New Orleans’ own K-Paul started it all, but the blackening craze has now spread nationwide. This is another great dish to make if you have run out of cooking oil—none is needed. Cooking time for the tuna in the recipe yields tuna that is medium-rare, still slightly pink in the center. If you prefer your tuna more well done, cook for an additional 30 seconds per side. You can substitute another meaty fish, such as salmon fillets, or chicken breasts (cook chicken for 4 to 5 minutes a side).
