Blue Cornmeal Waffles Recipe

0 Preheat the waffle iron.
1 Mix the flour, cornmeal, baking powder, baking soda, salt, and lemon zest. Set aside.
2 Separate the eggs carefully and set the yolks aside.
3 Whip the egg whites with the cream of tartar until they hold stiff peaks. Set aside.
4 Beat the egg yolks with the buttermilk and butter until well mixed.
5 Add the yolk mixture all at once to the cornmeal mixture and mix quickly -  just until batter is smooth.
9 Let the batter rest for a few minutes before folding in the egg whites and cooking to ensure the best texture.
6 Fold in half the beaten egg whites to loosen the mixture up.
7 Carefully fold in the remaining egg whites.
8 Pour about 3/4 cup of the batter onto the hot waffle iron and bake according to manufacturers instructions. The exact amount you need will depend on the actual waffle maker you use.
