Preheat the oil in a deep fryer to 350°F (180°C). Line a baking sheet with paper towels or a wire rack.
Batter
In a bowl, whisk together both flours, the cornmeal, sugar, paprika, baking powder and salt. Whisk in the milk, melted butter and egg until smooth.
Corn Dogs
Insert a popsicle stick into one end of each hot dog, leaving about 1 ½ inches (4 cm) sticking out of the bottom. Dip a few sausages at a time in the batter to coat well. Fry 3 sausages at a time in the hot oil until golden, about 5 minutes. Watch out for splattering. Drain on the baking sheet. Keep warm until ready to serve. Serve with mustard or ketchup.
