This is one of those not-measured recipes. It's one I made up. I use whatever different Cajun spices I can find. Soak the chicken in a mixture of one can of beer and Cajun spices (about two tablespoons) overnight in the fridge.
Then take it out of the beer/spice mixture and put on grill or in baking pan. Sprinkle more Cajun spices on it. Use leftover beer/spice to baste. Then grill or cook in the oven at 350 for one hour. Flavor is out of this world.
Lil' safety note: never serve a leftover marinade "raw" - nuke or otherwise heat to boiling for use as a dip. Also be careful about cleaning the grill transport platter in very hot water if using to serve later.
