Blue cornmeal gives these muffins a distinctive color and a natural nuttiness. Substitute yellow or white cornmeal for the blue, if necessary. If possible, scoop the batter over strips of dried corn husks to present the muffins more imaginatively. You can find husks in Mexican food sections or Hispanic markets. For a complementary topping, serve the muffins with sage-infused honey.
Preheat oven to 375F. Grease 12-muffin tin. If using corn husks, tear lengthwise into strips about 3Ú4 to 1 inch wide at widest point. Lay two strips overlapping in an ‘X’ in each muffin cup, with long ends jutting out above pan.
Cream butter and sugar with mixer or food processor. Add eggs, milk and cheeses, mixing well after each addition. Sift together flour, cornmeal, baking powder, salt and sage. Spoon dry mixture into batter about one-third at a time, mixing just until combined after each addition.
Scoop batter into prepared muffin tin, rounding at top of each muffin. Bake for 22 to 24 minutes, until toothpick inserted in center comes out clean. Serve warm or at room temperature.
