2 ears fresh corn
1 teaspoon olive oil
Salt and pepper, to taste
2 cups milk
2/3 cup cornmeal
2 large eggs, separated
1 tablespoon Dijon mustard
1 1/2 cups (6 ounces) Wisconsin Colby or mild Wisconsin Cheddar cheese, cut into cubes (1/2 inch)
Preheat the oven to 500° F. Rub the corn with the olive oil and season with salt and pepper. Arrange the corn on a baking sheet and roast, turning once, for 15 minutes. When cool enough to handle, cut the kernels from the cobs.
Lower the oven to 375° F. Butter a 1 quart soufflé dish or glass baking dish. In a medium saucepan, heat the milk until just boiling. Slowly add the cornmeal, whisking constantly. Cook the mixture, whisking, until thick and smooth, about 2 minutes. Transfer to a bowl and season with salt and pepper to taste. Let cool slightly. Stir in the egg yolks and mustard and combine well. Stir in the corn and cheese.
In a bowl with an electric mixer, beat the egg whites until they just hold stiff peaks. Gently fold egg whites into cornmeal mixture until just combined. Pour batter into prepared dish and bake in middle of oven until puffed and golden, about 40 minutes.
