1. Sift all of the dry ingredients together in a medium bowl.
2. Add the warmed egg and melted butter.
3. Then add about 1/2 of the milk, and whisk to blend the ingredients.
4. Add the remaining milk, and finish blending the ingredients. The batter will be fairly thin and smooth.
5. Pour the mix into the preheated iron and cook for 3 minutes 25 seconds.
Remove the waffle from the iron and place on a wire rack to cool. When the waffle has cooled below 49°C/120°F, place the waffle back into the iron to cook for 10 seconds longer. Serve immediately.
