Combine all ingredients except cornmeal and oil. Mash together between palms of hands or with a potato masher, and form into small, round croquettes. Roll each croquette in the cornmeal. Heat the oil in a large skillet. Fry croquettes for 2 minutes on all sides until golden, and drain on paper towels. These can also be made into patties, using less oil to fry on both sides.
To prepare the dipping sauce, mix all ingredients together and place in individual dipping bowls. Serve. Dip croquettes into dipping sauce before eating.
