Romantic Dinner - Tuna with Foie Gras
Ingredients
4 center-cut tuna steaks, about 6 ounces each, trimmed into the shape of a filet mignon
1 large white onion sliced ¼ inch thick
¼ cup olive oil (approximately)
2 large carrots, peeled and sliced very thin lengthwise into ribbons
2 medium-size zucchini, sliced very thin lengthwise into ribbons
2 tablespoons Brown Butter (see below)
Salt and freshly ground pepper to taste
4 ounces foie gras
Burgundy Butter Sauce (recipe follows)
Burgundy Butter Sauce:
1 cup balsamic vinegar
1 1/8cups red wine
1 shallot, cut in half
¼ cup (1/2 stick) cold unsalted butter; cut into tablespoon-size pieces
½ cup (1 stick) cold lightly salted butter; cut into tablespoon-size pieces
Brown Butter:
½ pound lightly salted butter
Instructions
1. Heat a 10-inch cast-iron skillet over high heat until very hot.
2. Moisten the onion slices with oil and lay in the hot skillet one layer deep. Cook until lightly charred, turn over with tongs, and char the other side. Remove from the pan and keep warm. Repeat until all the onions are cooked.
3. Meanwhile, bring about 2 quarts of lightly salted water to a rapid boil and drop in the carrot ribbons. Cook for 2 to 3 minutes, or until the carrots are tender but still al dente. Lift the carrots out of the water with a slotted spoon and place in a bowl. Using the same pot of boiling water, repeat this process with the zucchini ribbons. (Note: The zucchini will cook much faster than the carrots.)
4. To make the brown butter, in a heavy skillet over medium heat, melt the butter, stirring constantly. Increase the heat and continue stirring as the butter foams and begins to turn golden brown. Immediately remove the butter from the heat and carefully pour it into a heat-proof container.
5. Add the cooked zucchini to the carrots. Add the Brown Butter and season with salt and pepper.
6. Using a very sharp knife dipped in warm water, cut the foie gras into ½-inch thick slices. Sprinkle with salt and pepper and keep chilled.
7. Moisten the tuna steaks with oil and season with salt and pepper. Place into the same hot skillet used to char the onions. Sear for about 2 minutes on each side. Remove and keep warm.
8. In a smoking-hot 7-inch sauté pan, sear the liver slices on both sides for about 30 seconds, or just until a crisp outer crust forms. Remove and keep warm.
9. Quickly lay three or four charred onions in the center of each of four warm serving plates. Arrange two carrot ribbons and two zucchini ribbons over the onions in a nestlike pattern. Place a tuna steak on top, then finish with a slice of foie gras and a few charred onions.
10. To make Burgundy butter sauce, in a medium-size heavy bottomed saucepan, combine the vinegar, wine, and shallot over medium heat and reduce to a syrupy consistency.
11. Using a wooden spoon, incorporate the butter into the sauce one piece at a time. When all the butter is incorporated, remove the shallot pieces. Keep warm until ready to serve.
12. Sauce each plate with three pools of Burgundy Butter Sauce.
