Preheat the oven to 400°F.

Grease an 8-inch-square baking pan.

In a medium bowl, combine cornmeal, flour, 4 ounces grated Manchego cheese, sugar, baking powder, and salt.

Mince 1 tablespoon of pickled sliced jalapeño peppers.

In a small bowl, combine the minced jalapenos with milk, oil, and eggs; mix well.

Add the milk mixture to the flour mixture and stir just until blended.

Pour the batter into the prepared pan.

Lay the remaining jalapeno slices on top of the batter, spaced approximately 3 inches apart.

Sprinkle with the remaining 2 ounces of Manchego cheese.

Bake for 20 to 25 minutes, or until a wooden pick inserted into the center comes out clean.

Serve warm.
