This is a stretch, but I'm looking for this recipe that goes back to late 70's, early 80's. It was one of my favorites, but I've lost the recipe. Main ingredients were LOTS of chopped onion, 2 6 oz cans of tomato paste, worchestershire sauce, cider vinegar and sugar. It made a very thick sauce that was great on just about any meat. I contacted Bon Appetit', but their archives did not go back that far. Thought I'd see if any of you were familiar with it.
