In a small bowl, whisk together the eggs and lemon juice. Season the chops with salt and pepper. Just before you are ready to cook, dip the chops in the flour to coat both sides lightly. Shake off the excess. Heat a heavy 14-inch skillet over high heat. When the skillet is very hot, add 2 tablespoons of the olive oil and swirl to coat, then add the chops. Sear them on one side until you see bloody juices rising, 3 to 4 minutes, then turn and cook for about 30 seconds on the second side. Transfer to a platter and keep warm in a low oven. Pour off the excess fat in the skillet. Return the skillet to high heat, add the wine, and stir with a wooden spoon to release any flavorful bits stuck to the skillet. Add the stock or broth and simmer until reduced by one-third. Pour the reduced liquid into a bowl and wipe out the skillet with a paper towel. Return the skillet to moderately high heat and add the remaining 2 tablespoons olive oil. When hot, add the parsley and garlic and sauté briefly to release their fragrance. Add the artichokes and stir to coat with the seasonings, then return the liquid to the pan. Bring to a simmer, then remove the skillet from the heat and add the egg-lemon mixture. Swirl the pan constantly until the eggs thicken the sauce, which will happen quickly. Spoon the artichokes and sauce onto a warmed platter. Top with the lamb chops and serve immediately. |
