Menudo is a spanish dish. I first heard of it from some puerto rican frinds but in mexican restaurants they make it too. I live in Southern California and was shocked that it was so well know amongst my mexican neighbors, so on that note, I don't know if it's from the puerto rican or mexican region. I used to turn my nose up to it but I had some for the first time last night and I have to tell you, it was GOOD!!!! It's like a red sauce soup with onions, peppers and such in it, it is soooo good! I am going to eat some in a few minutes. My friend says to go to askjeeves.com to find some menudo recipes. I do believe the peppers, (Capsain)SP? is what helped.
If you don't mind me asking, were are you located?
