"This soup is a recipe of my friend's father who passed away a few years ago. It is soooo delicious I was shocked when I found out how easy it is to make!! the El Pato sauce called for in this recipe is easily found in the Mexican isle of your grociery store (unless you live in Queensland, Australia... can't find it here!! I have to have my sister send it to me from the U.S. just so I can make this soup!!) or at a Mexican market. Make sure to get the yellow can labelled "hot tomato sauce" or "salsa de chile fresco"..."
