Sounds like something I'd love to try soon:
Grand Marnier French Toast
6 large eggs
1/2 cup fresh orange juice
1/3 cup milk
1/4 cup Grand Marnier or other orange-flavored liqueur
1 and 1/2 tablespoon of brown sugar
1/2 tsp. cinnamon
8 slices whole-wheat bread -- best if slightly stale
3 tablespoons of butter for frying
Powdered sugar for dusting Preheat oven to 200F.
In a large shallow baking dish, whisk together eggs, orange juice, milk, liqueur, brown sugar, and cinnamon. Add 4 bread slices and soak 2 minutes. Turn slices over and soak 2 minutes more. Transfer soaked bread slices to a plate and repeat procedure with remaining 4 bread slices.
In a large heavy skillet or griddle, heat 1 1/2 T. butter over medium heat until foam subsides; cook half of coated bread slices until golden, about 3 minutes on each side. Transfer to a baking sheet and keep warm in oven. Cook remaining bread slices in same manner.
Dust French toast with powdered sugar and serve with warm maple syrup.
