I orginally found this in a very old Better Homes and Garden cookbook. It's been my family's favorite for years . . . try it and you'll see why! Use hotter chilis to achieve more spice. The brown sugar can be deleted for less sweetness. The Chili Sauce I use in the US, is a slightly sweet (not hot) sauce, believe it's made by Heinz (small fat jar). I have substituted pureed tomatos here in Mexico and it works great!
