Tuna Steaks With Caper Sauce Over Arugula

1½ teaspoons whole black peppercorns

4 fresh tuna steaks/fillets (about 1-inch thick, 6 ounces each)

¼ teaspoon salt

2 tablespoons extra-virgin olive oil

2 cloves garlic, thinly sliced

1 cup dry white wine, such as pinot grigio

2 to 3 tablespoons fresh lemon juice (from 1 lemon)

1 teaspoon anchovy paste

1 tablespoon capers, drained and rinsed

2 tablespoons unsalted butter

4 cups loosely packed baby arugula leaves

Place the peppercorns in a plastic bag and crack them coarsely using a mallet or rolling pin, or use a spice mill to coarsely grind them. Sprinkle the tuna steaks on both sides with the pepper and salt, pressing the seasonings in a little so they adhere.

Heat 1 tablespoon of the oil in a large heavy skillet over medium-high heat. Once the oil shimmers, add the tuna and cook for 1 minute per side (rare) or 2 to 3 minutes per side, if you like it done more. Transfer the fillets to a plate and cover loosely with aluminum foil.

Reduce the heat to medium; add the remaining tablespoon of oil to the pan. Add the garlic and cook for 30 to 60 seconds, until it has softened a bit and become golden. Do not let it brown, or it will become bitter.

Carefully add the wine (which will cause a lot of steam); increase the heat to high and cook for about 2 minutes, or until the wine has reduced by about half. Reduce the heat to medium; add the lemon juice (to taste) and anchovy paste, stirring to dissolve the paste. Once the mixture begins to bubble at the edges, add the capers and butter, stirring until the latter has melted. Remove from the heat.

To serve, place a cup of the arugula on each plate. Slice the tuna, then fan the slices atop each plate and drizzle with the sauce.
