Drain twelve sardines and cook in a chafing-dish until heated, turning frequently. Remove from chafing-dish. Make one cup Brown Sauce with one and one-half tablespoons sardine oil, two tablespoons flour, and one cup Brown Stock. Season with Anchovy essence. Reheat sardines in sauce. Serve with Brown Bread Sandwiches, having a slice of cucumber marinated with French Dressing between slices of bread.
