Seared Sea Scallops with Exotic Mushrooms, Potato Mousseline, Foie Gras Butter and Truffle Vinaigrette
- 4 ounces fresh foie gras
- 1/2 pound butter
- 2 tablespoons olive oil
- 3/4 pound wild or exotic mushrooms (shiitake, oyster, chanterelle, porcini, etc.) cut into bite-size pieces
- 1/2 pound peeled Yukon Gold potatoes, quartered
- 2 tablespoons milk, warm
- 12 large sea scallops
- 2 tablespoons chopped parsley
- 1 teaspoon lemon zest
- 1 teaspoon chopped garlic
- Truffle Vinaigrette:
- 1 can truffle juice (14 ounces)
- 1 can truffle peelings (5 ounces)
- 1 (8-ounce) bottle truffle oil
- 1 cup Ruby Port
- 2 cups extra virgin olive oil
- 1 tablespoon seasoned rice vinegar
- 1 tablespoon sherry vinegar
For the wild mushrooms: Heat a large saute pan over a high heat (large enough to hold all the mushrooms in a single layer). Add 1 tablespoon olive oil and then the mushrooms. Cook over high heat until crispy around the edges -- approximately 3 to 5 minutes. Remove the mushrooms from the pan and let cool.
For the Potato Mousseline: Place potatoes in a saucepan, cover with cold water and bring to a boil over medium heat. Reduce the flame to low and simmer until very tender. Drain immediately and place in a food mill (not a food processor) or potato ricer. Rice or work through the food mill, adding 1/4 pound of butter, stirring constantly. Add 1 to 2 tablespoons of warm milk so that the puree is silky but not runny. Cover with plastic wrap and keep and keep wamr over a double boiler.Truffle Vinaigrette:
Combine truffle juice, port and the juice from the truffle peelings in a non-reactive saucepan. Reduce over medium-low heat until reduced by about 3/4 or until liquid is a thin syrup. Remove from heat and cool.
Combine port - truffle reduction with vinegars and whisk in the oils. Set aside. This mixture will keep for 1 month in the refrigerator if it is tightly covered.
For the Gremolata: Combine chopped parsley, lemon zest and garlic.
Sear the scallops: Heat a saute pan over high heat. Season scallops with salt and pepper. Add 1 tablespoon oil to the pan. Sear the scallops until golden on one side, flip and then sear the other side. Remove from pan and keep warm.
In the center of 4 large plates place a dollop of the potato mousseline. Reheat the mushrooms and sprinkle with gremolata to taste. Arrange mushrooms around the potatoes. Drizzle the foie gras butter over and around the mushrooms. Drizzle the truffle vinaigrette on and around the mushrooms. Place 3 scallops on top of each of the mounds of potato ,mousseline.
