Combine the cornmeal, white and whole wheat flours, sugar, baking powder, baking soda, and salt in a medium bowl
In a smaller bowl, beat the egg then stir in the orange zest, orange juice, and buttermilk. Stir in the melted butter.
Pour the liquid mixture into the dry mixture and whisk quickly to blend the ingredients thoroughly. Do not overbeat. Stir in the blueberries.
Heat a skillet or griddle over medium-high heat. If it is non-stick you will not need oil or butter. If not, melt some butter in the pan and coat. When the skillet is nice and hot, lower the heat slightly to medium and spoon the batter onto it using about 2 tablespoons of batter per pancake.
Cook until bubbles appear on the surface and the edges look cooked then flip once and cook until done.
Serve with your favorite tasty toppings - butter, pure maple syrup, coconut flakes, toasted pecans - the list goes on.
