Preheat the waffle cone iron.

Beat the egg, egg white and salt in a small bowl with a fork until well blended.

Beat in the sugar and beat until sugar is well-incorporated.

Add the flour and stir slowly and completely.

Spoon about 3 tablespoons of batter in the center of the iron.

Cook for about 1 minute.

Quickly remove the waffle from the iron onto a paper towel.

Use the paper towel to help wrap the hot waffle around the molding cone.

Hold the waffle in place for a few seconds for the cone to cool and take the shape of the mold.
