Fresh Corn Fritters

4 lg. ears corn
2 eggs, separated
2 tbsp. all-purpose flour
1 tbsp. sugar
Salt and freshly ground pepper
Unsalted butter

Cut the kernels from two ears by standing each ear upright on a plate, carefully slice beneath the rows in a steady downward motion. With the back of the knife, scrape the cobs to extract the juice. Grate the kernels from the remaining 2 ears, cutting off the kernels at just half their depth and scraping off pulp on the cob. Put all the corn kernels, pulp and juice into a bowl. The mixture will resemble scrambled eggs. Beat the egg yolks in a large bowl until light. Beat in the flour, sugar, salt and pepper to taste. Stir in the corn. Beat the egg whites in a large bowl until stiff. Fold them into the corn mixture. Heat a heavy skillet or griddle over medium heat and grease it lightly with butter. Drop the batter by small spoonfuls onto the skillet and cook until golden. About 30 seconds each side. Transfer the cooked fritters to a lightly buttered serving platter and keep them warm in a low oven while cooking the remaining fritters.
