UPDATE! There must be something in the air because The Old Grey Lady also published a recipe for beer can chicken this week. I like the recipe below from L Magazine, though.

Steve Hindy, Brooklyn Brewery founder & president, actually told me that this was one of his favorite recipes. L Magazine provides a colorful step by step guide to preparing a delicious whole chicken with a can of Brooklyn Lager firmly positioned in its largest orifice.

My wife and I debated the point all weekend: Is the cavity in a chicken the neck opening or the butt? Turns out it’s the butt. Once that was settled we procured a fresh chicken from Marlow and Daughters, fired up the grill and lodged a can of beer in its ass. Hence: Beer Ass Chicken. Or as it’s more often known, Beer Can Chicken.
I felt a certain evolutionary guilt about sticking a metal can up a fellow creature’s exit hole, and wished things had turned out differently in the neck vs. ass debate. But what’s done is done, and the incredibly moist and tender result eased my conscience.
My recipe is a modified version of Pat Neely’s, of Memphis barbecue and Food Network fame. Because yes, I have a thing for cooking shows with painfully canned banter (we all have our embarrassing vices: Conklin has golf; I have the Down Home With the Neelys [Ed.—I also count Down Home With the Neelys as a vice, for what it's worth.]). But do the Neelys use dark brown sugar and ground mustard? No they don’t, because doing so would be too extreme for the Food Network. Ok, it’s actually not that extreme, but I needed to make this recipe my own, and the brown sugar gives the chicken a nice charred and crispy caramelized crust. So without further ado, go make a Beer Ass Chicken this weekend:
INGREDIENTS:
For the rub:
Keep in mind these are rough estimates.
-1 tablespoons smoked paprika (careful – stuff’s powerfully smoky)
-2 tablespoons salt
-2 tablespoons onion powder
-1 tablespoon dark brown sugar (go easy here, otherwise the sugar can burn)
-1 tablespoon garlic powder
-1 tablespoon cayenne pepper
-1 tablespoon ground mustard
-1 tablespoon cumin
-2 teaspoons dried thyme
-2 teaspoons dried oregano
-2 teaspoons black pepper
For the Chicken:
-1 4 pound chicken, give or take a pound
-Vegetable oil
-1 12-ounce can of beer*
*A note on the beer: I like to use a medium-bodied lager with some malty sweetness to it for extra flavor; something like Brooklyn Lager, which does come in cans if you look hard enough. In reality it probably doesn’t matter what you use since the beer is mainly just a water source to help steam the chicken and keep it moist. But beer is more fun than soda, so you know, stick with beer.
