sauce, 1 teaspoonful of Harvey's sauce, 1 teaspoonful of good mushroom ketchup, 1/2 glass of port wine or strong ale, pepper and salt to taste, a little flour to thicken, 1 onion finely minced, a few slices of cold roast beef. _Mode_.--Put all the ingredients but the beef into a stewpan with whatever gravy may have been saved from the meat the day it was roasted; let these simmer gently for 10 minutes, then take the stewpan off the fire; let the gravy cool, and skim off the fat. Cut the beef into thin slices, dredge them with flour, and lay them in the gravy; let the whole simmer gently for 5 minutes, but not boil, or the meat will be tough and hard. Serve very hot, and garnish with sippets of toasted bread. _Time_.--20 minutes. _Average cost_, exclusive of the cold meat, 4d. _Seasonable_ at any time. II.
