Place the milk together with the butter, blood orange zest and juice in a medium sauce pan and heat on low until lukewarm. Set aside.
In a mixing bowl, whisk together the all-purpose flour, sugar and sea salt. Make a well ; add the eggs one at a time. Gently start mixing inwards going outwards with your mini whisk. Add the warm milk/butter/orange mixture, a splash at a time while continuing mixing. Finally, add the Grand Marnier. Mix until it is all incorporated.
REST (NOT NECESSARY)
Let your batter rest covered with a plastic wrap at room temperature for about 30 minutes.
BLOOD ORANGE BUTTER
In a small bowl beat the softened butter, the sugar, Grand Marnier and blood orange zest together. Set aside.
COOK!
Heat your Pancake pan on Medium 5 minutes prior starting making your "Crêpes" and slightly oil the surface with a kitchen towel.
Pour one large scoop of batter in your pan, spreading it over with your spatula.
Once one side is cooked, flip it over. Cook it for a few seconds more. Then, serve with the blood orange butter on top. Enjoy & Bon Appétit!
