• To make the waffle batter simply mix all dry ingredients in a bawl, then add the egg, the yogurt and the oil and mix until well incorporated. 
• The batter will be thick, so fold in gently one beaten egg white to lighten it up. The egg white should be beaten until stiff picks are formed. 
• Once the batter is ready, bake it in your waffle machine for a minute or two, according to your waffle maker’s instructions. 
• To make the orange curd, combine the yolks and the sugar in a saucepan over a low heat, and mix to combine. 
• Add the orange juice and stir constantly with a wooden spoon, for about 8-10 minutes. 
• Remove from heat and add a little bit of butter in it. 
• To get thicker consistency let the curd cool down, however with this recipe I never have the patience to wait:)
