1 Muscovy duck breast (about 1 pound)
1 tsp. salt
4 garlic cloves, smashed to a paste, with a little salt
1 tsp. coarsely crushed peppercorns
Parsley salad (recipe follows)

With a sharp knife, remove the tenderloin from the underside of the duck breast and reserve for another purpose. Trim any ragged bits or gristle. Turn the breast over and trim any excess fat from the edges. Score the skin by making shallow diagonal cuts, 1/2 inch apart, in one direction and then repeating in the other direction, creating a diamond pattern. Season on both sides with the salt, then massage with the garlic paste. Press the crushed peppercorns evenly over both sides. Put the duck on a platter and leave to marinate for at least 1 hour at room temperature, or refrigerate overnight (if the latter, bring to room temperature before cooking).. Heat a cast-iron skillet over medium-high heat. After 5 minutes, when the pan is hot, carefully add the duck breast skin side down and let it begin to sizzle. Using tongs, check to see that the skin is not browning too quickly, and reduce the heat as necessary. Be careful: The duck breast will render a fair amount of hot fat. The skin should be golden and crisp after 6 or 7 minutes. Turn the breast over and cook for 2 minutes more. Remove to a carving board and let rest for 10 minutes. (When the rendered duck fat has cooled a bit, strain into a jar and save for future use). Cut at an angle into 1/4-inch-thick slices and arrange on a platter. Top with the parsley salad and serve. Serves 2 to 4.

To make the parsley salad:

1 large bunch flat-leaf parsley
2 tsp. lemon juice
Salt and pepper
1 small garlic clove, minced
2 tsp. olive oil
A chunk of Parmigiano-Reggiano cheese for shaving (optional)

Pick the parsley leaves from the stems—you want about 2 C. Wash and gently dry with a clean towel. In a small bowl, whisk together the lemon juice, salt and pepper to taste, garlic and olive oil. The parsley leaves must be dressed at the very last minute. Season with a sprinkle of salt, then toss with the dressing to coat lightly and serve in a fluffy pile. Garnish with shavings of Parmesan, if desired
