This recipe originally came from the Chevy's and Rio Bravo Cookbook. I've made it for about ten years, for groups as large as 50 who all raved about its flavor and authenticity. The Achiote Paste can be found at Latin grocers, or by mail at MexGrocer.com. It's a little bit of work but well worth it. It's essential to use fresh orange and pineapple juice, for the enzymes, if at all possible. Time listed includes the marinating time.
