Traditional recipe with ingredients that have been updated to ones more accessible to us in the USA but this is the same recipe and method used by Mexican families for generations! (The soy sauce is a recent AND YUMMY addition) I saw an Alton Brown show recently in which he used this same method of cooking! The hair dryer is a new generation update- in the 'old days' they just fanned the flames to rid the ashes. UPDATE: 9/2009 Due to a review that this was a little to sweet I have edited the recipe with that in mind. Please adjust the amount of onion and sweetness to your personal taste. Thanks Steph for the input! I do appreciate it! I always enjoy others opinions and ideas!
