This is a variation of a recipe I saw on Good Eats. Man this stuff is hot and good. Put it on grilled chicken, pork, beef, an old shoe... My favorite is to serve this with green peas. Don't ask me why.
A great marinade for beef. I like to leave beef tenderloin in this marinade at least 8 hours. The key is the chipotle peppers. Smokey and spicy. Look for the chipotle peppers in adobo sauce in your mexican food isle.
