1/2 cup sugar
1 tablespoon ground cinnamon
oil for frying
4 ounces spiral-shaped duros
Combine sugar and cinnamon in a bowl and stir.
Heat oil to 350 degrees Fahrenheit.
Place about 15 pieces in at once, and cook. Nothing will happen for the first few seconds, then suddenly they will puff up. Cook for 5 seconds after they have puffed up.
Move to a wire rack to drain, and sprinkle cinnamon and sugar over these very liberally.
