This is an easy recipe for American hot dogs that lets you recreate that familiar taste from convenience store checkouts at home. Mix baking powder, sugar, salt, all-purpose flour, oil, water, and egg to make the batter, then let it rest in the refrigerator. Dip sausages generously in the batter and fry them in oil at 170-180 degrees Celsius for just over 2 minutes. Tips such as dusting the sausages with flour and frying them tip first will result in American hot dogs that look and taste authentic. You can enjoy any leftover batter as mini donuts.
