How to Make It
Pour oil to a depth of 3 inches into a large heavy saucepan; heat over medium-high heat to 365°F.
Combine cornmeal and next 4 ingredients in a medium bowl; make a well in center of mixture. Stir together egg, milk, and onion; add to dry mixture, stirring just until moistened.
Drop batter by tablespoonfuls, 6 at a time, into hot oil. Fry 2 minutes or until browned. Drain on a wire rack over paper towels. Serve with tartar sauce, if desired.
