Lamb:
Soak the currants in warm water for 30 minutes. Drain.
Heat 1 tablespoon of the olive oil in a 6-quart saucepan over high heat. Add the
lamb, cinnamon, ginger, allspice, cayenne, and salt and pepper and cook,
stirring to break up the meat, until browned, about 5 minutes.
Transfer the lamb to a large strainer set over a bowl and drain; discard
any liquid left in the pan. Return the pan to the heat and add the remaining 3
tablespoons olive oil and heat until it begins to shimmer. Add the onions and
bell pepper and cook until soft, about 5 minutes. Add the serrano and garlic and
cook for 1 minute. Add the tomato paste and cook for 1 minute.
Return the lamb to the pan, add the wine, and cook, stirring occasionally, until
almost completely evaporated, about 5 minutes. Add the tomato puree and currants
and bring to a boil. Reduce heat to low and simmer until thickened, about
30 minutes. Stir in the parsley and oregano, salt and pepper and honey to taste.
Remove from the heat.
Eggplant:
Heat the canola oil in a 12-inch skillet over medium-high heat. Season the
eggplant slices on both sides with salt and pepper. Working in batches, add the
eggplant slices and fry until tender and lightly golden brown on both sides,
about 5 minutes. (or bake or grill) Transfer the eggplant slices to paper
towels.
Bechamel:
Melt butter in a medium saucepan over medium heat. Add flour and cook, whisking
constantly, until pale and smooth, 2 minutes. Still whisking constantly, add the
milk and bay leaf and cook until thickened. Season with salt, pepper, and nutmeg
and discard the bay leaf. Let cool for 5 minutes. In a small bowl, whisk
together the egg yolks, goat cheese, and lemon zest and whisk into the bechamel
sauce until smooth.
Oven to 400 degrees F. Butter a 3-quart baking dish or casserole dish.
Put half the eggplant slices in the dish and cover with half the meat sauce. Top
the sauce with the remaining eggplant slices, and then the remaining meat sauce.
Pour the bechamel over the top of the meat sauce and spread evenly with a rubber
spatula. Sprinkle Romano evenly over the top, place the dish on a baking sheet,
and bake until browned and bubbly, 45 to 50 minutes. Top with more chopped
parsley, Let cool for at least 20 minutes before serving.
