Beef Stroganoff

Trim fat from meat. Slice meat lengthwise into thirds. Moisten slices on each side. Sprinkle with tenderizer. Then cut each slice, across the grain, into very thin strips. In a large heavy skillet melt 1 tbs butter. Over high heat sear meat on all sides. Remove meat as it browns and set aside. In remaining hot butter in skillet saute onion and garlic, about 5 minutes. Remove from heat. Add flour, meat extract paste, ketchup, salt and pepper. Stir until smooth. Gradually add beef broth. Bring to boiling, stirring, then simmer 5 minutes. Over low heat add dill, soup and sour cream, stirring until well combined. Add mushrooms and meat. Simmer slowly just until sauce and meat are heated through. Serve with rice or egg noodles. Sprinkle with parsley.
