Blend 2 tbs melted butter and flour in a sauce pan. Gradually add fish or vegetable stock, stirring constantly, and let simmer for a few minutes. Beat together cream and eggs. Stir a little of the hot sauce into this mixture. Add to the sauce stirring vigorously. Let the sauce simmer, stirring constantly until it thickens. Remove from fire and add butter (1-2 tbsp) in small pieces.
Finally, add seasonings, shrimp and dill. Divide the mixture on each pancake. Roll the pancakes and arrange in a greased baking dish. Sprinkle with grated cheese and dot with butter. Bake in 375F oven for about 10 minutes. Serve as hors d'oeuvres.
