In a mixing bowl, whisk together the dry ingredients: flour, sugar, baking powder, and salt.

In another bowl, combine the wet ingredients: milk, blood orange juice, blood orange zest, egg, and melted butter.

Pour the wet ingredients into the dry ingredients and mix until just combined.

Preheat a griddle over medium heat and lightly grease it.

Pour 1/4 cup of batter onto the griddle for each pancake.

Cook until bubbles form on the surface, then flip and cook until golden brown.
