Haven’t had this in a while, but Sal’s Sassy Sauce (NY chicken chain) is like a mustard based sweet and sour sauce. With the love mustard has been getting on these condiment threads, some of you may be interested.
Here’s the closest recipe I can find to the one I’ve used, though my recipe has yellow mustard instead of Dijon. I feel yellow mustard is most like the original. I don’t think it would get the right color with Dijon.
This recipe is fairly large, but the amounts look like they should 1/4 easily. I made the whole thing and put it in a squeeze ketchup bottle.
Try it on anything you’d like a sweet or honey mustard on.
