Stir the cornmeal mixture into the liquid mixture but do not beat. A few lumps will be fine, but make sure there is no flour at the bottom of the bowl.
Fold in the corn kernels, minced jalapeño and optional cheese.
2 tbsp minced jalapeños, ½ cup grated Cheddar or Monterey Jack cheese, 1 cup corn kernals
Spoon evenly into pre-greased muffin pan; each cup should be about 80% full. Bake for about 20 minutes or until well risen and pale golden brown.
Notes
Makes 12 muffins; nutrition is for a single muffin (including the cheese)
