Preheat the broiler.
Place the cooked french fries onto a plate. In a small saute pan, combine the Imperial Sauce and crab and bring to a simmer. Pour over the fries and place under the broiler until the sauce starts to bubble and turn golden brown, 30 to 60 seconds. Remove the fries from the broiler and garnish with lemon wedges and parsley.
Begin by making a bechamel sauce. In a 4-quart saucepan set over low to medium heat, add the butter and melt. Stir in the flour until a paste forms, and then cook for 3 to 4 minutes to achieve a blonde roux. Slowly whisk in the milk to avoid forming any lumps and bring to simmer. Cook for 30 minutes to cook out the flour taste.
While the bechamel sauce is cooking, in a separate bowl combine the mayonnaise, lemon juice, egg yolks, Worcestershire sauce, dry mustard, cayenne pepper, celery salt, salt and black pepper, and whisk until fully incorporated.
After the bechamel sauce has simmered for 30 minutes, SLOWLY pour the sauce into the egg mixture while whisking. If the bechamel sauce is added too fast, the eggs mixture will scramble. Allow the sauce to cool, and then refrigerate for at least 8 hours to allow the flavors to blossom.
