Mustard Seed Dressing (recipe follows)
1 1/2 pounds center-cut Ahi tuna or 4 (4 to 6-ounce) 1-inch thick sushi quality tuna steaks
1 teaspoon coarse sea salt
2 teaspoons black peppercorns
1 teaspoon white peppercorns
2 teaspoons fennel seeds
1 1/2 teaspoons dried culinary lavender flowers
3 tablespoons extra-virgin olive oil
4 cups savory mixed fresh salad greens and herbs
Prepare Mustard Seed Dressing; set aside.
If using the center-cut Ahi tuna, trim and cut the tuna into a block approximately 2 inches across; then cut into 1-inch steaks.
Crush the salt, peppercorns, fennel seeds, and lavender with a mortar and pestle or a rolling pin. Lightly oil the tuna with 2 teaspoons of the olive oil; evenly coat the tuna with the lavender-pepper mixture, patting off any excess.
In a heavy bottomed sauté pan or a cast-iron pan, heat the remaining 1 tablespoon olive oil. Increase the heat to high and place the tuna in the pan. Sear for 1 minute, then turn over carefully, reducing the heat to medium. Sear the other side for 1 more minute until medium rare. Remove from heat and immediately refrigerate the tuna for at least 1 hour but no more than 3 hours.
To serve, arrange the greens on chilled individual serving plates. Drizzle with Mustard Seed Dressing. Thinly slice the tuna and arrange on top of the dressed greens.
Makes 8 servings.
Recommended wine: Fume/Sauvignon Blanc offers some balancing acidity to the peppery, mustardy flavors in the dish. A young, vibrantly fruity Pinot Noir works beautifully as a red wine accompaniment.
