FOR THE SAUCE: Melt butter in a 2 quart saucepan over medium heat. Add flour. Cook and stir for 5 minutes(should have a nutty aroma). Add 1/2 tsp white pepper. Stir in 2 tbsps lobster base and cook for an additional minute. Add milk & wine. Add 2 oz. of the cheese. Continue to cook until thickened. FOR THE CRAB MIX: Lightly chop the flaked imitation crab. Combine with shrimp in a medium size bowl. Add 1.5 cups of cold sauce. Mix well. FOR THE ENCHILADAS: Lay out the tortillas on a flat surface. Place 2 to 3 heaping tablespoons of the crab mix across the center of each tortilla. Place flap of the tortilla over the crab mix and roll. Place flap side down onto a plate or in your baking dish. Ladle warm sauce over the enchiladas. Top with remaining monterey jack cheese. Put into a preheated 425 degree convection oven for 12-14 minutes.
