In a small bowl combine ketchup and pickled peppers. Mix well and set aside.

In a large mixing bowl, combine egg, corn muffin mix, garlic powder, onion powder and milk. In a separate shallow dish add flour. Insert wooden skewers half way into cocktail franks.

Heat oil to 375 degrees F in a deep-fryer. Dredge each cocktail frank in flour, dust off excess then dip into cornmeal batter. Fry 2 to 3 corn dogs at a time for about 1 to 2 minutes or until golden brown. Drain on paper towels. Serve warm with the relish.
