Its a bit off topic, but still. I have to agree with the beer usage, the beer is essential with the barbecueing of pretty much anything. If you havent used beer on roasting pork on open flame/grill u dont know what good barbey is!!!
Try it, believe me, youll like uit for sure.

Just pour some of that beer you r drinking over the meat and the fire for that matter when its half done....it keeps the moisture and the flavour inside!
