In a large bowl, combine the flour, eggs, melted butter, warm milk, salt, sugar, cinnamon, and nutmeg. Whisk until combined.
Heat a non-stick pan over medium heat. Grease the pan lightly with butter or oil. Using a ladle, pour the batter into the pan. Swirl the pan around so the batter covers the bottom of the pan.
Cook the crepe for about 2 minutes on each side, or until golden brown. Remove from the pan and set aside.
In a medium saucepan, combine the orange zest, orange juice, sugar, melted butter, and orange liqueur (if using). Bring to a boil and simmer for about 5 minutes, stirring occasionally.
To assemble the blintzes, spoon about 2 tablespoons of the orange filling into the center of each crepe. Fold the crepe over the filling and place it seam side down on a plate. Drizzle with the orange sauce.
