Crepes: In a medium bowl, mix together all of the crepes ingredients. Cover and refrigerate for a few hours, or overnight.
To a small, non-stick pan (crepe pan), coat with butter and put over medium heat. Pour about 2 ounces of batter in the pan and lift the pan off the heat, tilting in a circular motion until the batter forms a nice and even thin layer. Cook until top is firm and bottom has set. Turn the crepe over and cook until firm. Remove the crepe and begin a new one. Repeat with all of the remaining batter. Lobster Champagne Sauce: Sweat the onions, carrots, celery, shallots, and garlic in a medium saucepan with clarified butter for about 5 minutes. Add the white wine and reduce by half. Then, add the lobster base and water and let simmer for about 5 minutes longer. Strain the mixture and put back in saucepot. Add the heavy cream and cook for 5 to 10 minutes. Add the champagne and cook for 2 minutes. Incorporate the roux and bring back to a simmer to thicken. Season with white pepper, to taste.
Filling: In a medium saute pan, add the clarified butter. Add the seafood and let the shrimp cook through, about 3 minutes. Add the champagne and reduce for 1 minute. Add the lobster champagne sauce and let cook for another 2 minutes. Fold in the diced tomatoes and scallions and season with salt and pepper. Mixture is ready to serve.
Take 2 crepes and fill with some of the mixture and roll the crepes. Place in a shallow gratin dish. Repeat with the remaining ingredients. Add the remaining sauce and seafood on top of the crepes.
