Bone Marrow Flan With Steak Recipes

ROASTED BONE MARROW WITH PARSLEY TOPPING

Steps:

• Fill a large 4- to 6-quart container with 6 cups cold water and whisk in 2 tablespoons of the kosher salt to dissolve. Add the marrow bones, cut-side down, and top with the ice. Refrigerate for 24 hours.
• When ready to cook, preheat the oven to 425 degrees F and place a rack in the center position.
• Drain the bones and pat dry with paper towels. You want the bones to cook as level as possible to minimize the loss of fat as it renders out, so place them cut-side down on a small sheet pan. Cover with a generous layer of aluminum foil, then use your hands to mold the foil around the bones and sides of the pans. Place a second pan on top of the foil, then flip the whole apparatus over. Remove the sheet pan that is now on top to reveal the bones, cut-side up, and nestled in foil. They should be pretty close to dead level.
• Roast the bones for 8 minutes, then rotate the pan and continue roasting until the bones have browned and the marrow is spreadable and soft, but not melted, 15 to 18 minutes total.
• While the bones roast, make the parsley topping. Whisk the oil, lemon juice, and a pinch of salt together in a medium bowl. Add the parsley leaves, celery leaves, celery stalk, lemon peel, shallot, garlic, and capers and toss to combine.
• When the bones are finished, immediately dose about a third of the parsley mixture over the marrow and wait 5 minutes. Then, carefully transfer to a platter and serve with the toast, flaky salt, and remaining parsley mixture.

BONE MARROW FLAN WITH STEAK

Steps:

• Chill the marrow bones at least one hour. Using a long thin knife, cut around the inside surface of the bone, and push out the marrow in one piece. Place the marrow in a bowl of cold water, and refrigerate at least 3 hours, up to 24 hours.
• While the marrow is refrigerated, place the empty bones in a pot and cover with water. Simmer until all the fat and meat can easily be scraped away, about 2 hours. Remove the bones from the water, scrape them clean, and set aside.
• To prepare the flan: In a small nonreactive saucepan, combine the shallots and wine. Bring to a simmer, and cook until almost all the wine has evaporated, about 30 minutes. Remove from the heat and allow to cool. In the container of a blender or food processor, combine the cream, eggs, and shallot mixture. Puree until smooth. Season to taste with salt and pepper. Strain through a fine strainer, and set aside.
• Preheat oven to 300 degrees. Place teakettle of water over high heat to bring to a boil. Wrap the bottom half of each bone tightly, first with plastic wrap, then with foil. Stand each bone up in a deep roasting pan with the foil on the bottom. Pour the flan mixture into each bone, filling them up halfway. Cover the pan with a lid or heavy-duty foil, and place in the oven. Bake for 45 minutes. Remove from the oven but keep in the pan.
• Prepare a hot grill or broiler. Remove the marrow from the ice water, and cut into slices 1/2 inch thick. Grill or broil the steaks to taste. While the steaks are cooking, place the milk in a small skillet over low heat and bring to a slow simmer. Add the marrow slices, and poach until the surfaces are smooth and they are heated through, about 5 minutes.
• To serve, place each steak on a plate. Carefully remove the foil and plastic from each bone, and place a bone, flan side down, on each plate. Fill the empty top halves of each bone with the poached marrow slices. Serve immediately.
