Ingredients

4 skinless salmon fillets (5 ounces each, about 1 inch thick)

1 leek, halved and rinsed well

1/2 teaspoon whole peppercorns, plus freshly ground pepper

Coarse salt

2 tablespoons thinly sliced basil leaves, plus sprigs for garnish

1 teaspoon finely grated lemon zest and 1/4 cup lemon juice (from 2 lemons)

1/2 teaspoon sugar

1/3 cup extra-virgin olive oil

2 cups shelled fresh garden peas (from 2 pounds in pods)

1 tablespoon thinly sliced fresh mint leaves

Preparation

Place salmon in a pot, and add leek, peppercorns, 2 teaspoons salt, and 4 cups water. Bring to just under a boil, reduce heat, and cook at a bare simmer until salmon is just cooked through, 3 to 5 minutes. Remove from water, and cover with parchment to keep moist.

Puree sliced basil and lemon zest in a food processor. Add sugar and lemon juice, and pulse to combine to make vinaigrette. With machine running, add oil and season with salt.

Bring a medium pot of water to a boil. Add 1 tablespoon salt and the peas. Reduce heat, and vigorously simmer until tender and bright green, about 4 minutes. Drain, and transfer to a bowl. Add 2 tablespoons basil vinaigrette, and crush with a potato masher. Season with salt and pepper, then add mint.

Divide peas among 4 plates, and top with salmon. Drizzle with more vinaigrette, and garnish with basil sprigs.
