Try bacon grease instead of vegetable oil. Take your time with the roux, cook it over medium heat. It takes me about 3 Abita Ambers to finish a roux, I assume on the island that would be 3 belikin's.
Mudbug,
the assumption is good, but incorrect. Belikins are little beers, so you're looking at at least four of them to equal three real beers.
