1 cup heavy cream
1/2 cup plus 2 teaspoons all-purpose flour
2 tablespoons finely chopped shallot
1 tablespoon unsalted butter
1 (10-oz) package frozen chopped spinach, thawed and squeezed dry
1/8 teaspoon freshly grated nutmeg
1 teaspoon salt
1/2 teaspoon black pepper
1 1/2 cups coarse fresh bread crumbs (from firm white bread)
4 poached large eggs>
3 oz thinly sliced serrano ham or prosciutto
7 to 8 cups vegetable oil
1 large egg, lightly beaten with 1 teaspoon water

Whisk together cream and 2 teaspoons flour in a small bowl until just combined. Cook shallot in butter in a 9- to 10-inch heavy skillet over moderately low heat, stirring occasionally, until shallot is softened, about 3 minutes. Add spinach, nutmeg, 1/2 teaspoon salt, and 1/4 teaspoon pepper and cook, stirring constantly, until excess liquid is evaporated, about 2 minutes. Stir cream mixture, then add to spinach and cook, stirring occasionally, until cream is slightly thickened, about 2 minutes. Remove from heat. Stir together bread crumbs, 1/4 teaspoon salt, and 1/8 teaspoon pepper in a shallow bowl. Spread remaining 1/2 cup flour on a plate and set aside for dredging. Gently blot any water from top of poached eggs with paper towels, then sprinkle with remaining 1/4 teaspoon salt and 1/8 teaspoon pepper. Carefully dredge 1 poached egg in flour, dusting off excess. Transfer to beaten egg, spooning to coat completely, then transfer with a slotted spoon to bread crumbs, letting excess egg drip off. Coat with crumbs and transfer to a plate. Repeat with remaining poached eggs, 1 at a time. Cut sliced ham crosswise into 1/4-inch-wide strips. Heat 1 1/2 inches oil in a 3- to 4-quart heavy saucepan (about 1 1/2 inches deep) over high heat until deep-fat thermometer registers 375°F. Fry ham in oil, stirring occasionally with a clean slotted spoon to separate strips, until crisp, 15 to 20 seconds. Transfer ham to paper towels to drain. Return frying oil to 375°F. Lower 2 eggs (1 at a time on slotted spoon) into hot oil and fry until golden brown, 15 to 20 seconds. Transfer fried eggs to paper towels to drain. Repeat with remaining 2 eggs. Reheat spinach over low heat, stirring constantly and adding more cream or water to loosen mixture if necessary, about 1 minute. Divide creamed spinach among 4 plates, then top with poached eggs and ham.
