For a decent stretch of time now, my family has bought this tomato sauce. It does not have any ducks in it at all, we just call this "Duck Sauce" because of the one on the cover. We swear by this stuff. It's essentially a tomato sauce with some heat. You can make some yourself quite easily, if you'd prefer.
I'll update this page later on with a recipe, if I can find or develop a good one.
Take care,
