In a saucepan, mix vinegar, water, sugar, mustard, butter, lemon, onion, and seasonings. Simmer, uncovered, 20 minutes. Add worcestershire sauce and catsup, bring back to a boil and its done. (Good Housekeeping CB, 1955)

NOTE: I do not use cayenne or salt and always double this recipe. Into the double recipe, I add about 1/4 to 1/3 cup brown sugar. This gives the sauce more of a sweet and sour taste. It is just excellent on Baby Back Ribs, which I simmer in water with a little vinegar, garlic and just a pinch of salt for about 30 minutes before barbequeing. Through trial and error, I have found that Heinz catchup is thicker and makes a "clingier" sauce.
