Here we sit at the very cusp of grilling season. Spring has sprung, and it's time to get outside. To long have I stared out the kitchen window at my Weber siting lonely next to the garage.
I've decided to start the season with a whole chicken, butterfly cut. This is ideal for grilling because it flattens the chicken out, and exposes more surface area to the direct heat of a grill. There are easier ways to roast a chicken on a grill with indirect heat. My brother loves to cook a chicken on a grill with a can of beer shoved up it's butt. However, we all crave variety. Butterflying a chicken will give you a very tasty bird with great presentation. Serving up a whole chicken with a bunch of nice grill marks on it is sure to impress most people.
Warning: The following pictures can be a little graphic if you've never seen someone brutalize(cut-up) a chicken before. Proceed with caution.
We start with a whole chicken. Don't go for the biggest chicken you can find because the final product will be to thick, and take forever to cook. Probably leading to a burnt exterior. The reason we are butterflying in the first place is flatten the chicken, causing it to cook more quickly throughout. Get a nice heavy duty knife or cleaver and a solid cutting surface. Place chicken breast side up on the cutting board.

Start cutting along one side of the back bone. You will have to cut through all the rib bones. This will be a little difficult. Don't be afraid to use some muscle and be careful not to slip. Kitchen scissor are helpful at this point, also.

Cut along other side of backbone, completely severing it from the chicken. Either discard backbone, or place it in a Ziplock bag in the freezer and use it later for making stock.

Next, we have to remove the keel bone. This is a bone that runs down the middle of the breasts. I made a few markings on this picture to illustrate key areas. The blue lines are where you need to make a "V" cut, releasing the head of the keel bone. The red lines represent the two pieces of cartilage that attach the keel bone to the ribcage. You need to cut through these also. Next, get your thumbs underneath the keel bone on either side and run them down the length of the bone, where I've placed the green lines. The chicken will pull away from the sides of the keel bone fairly easily

Here you see the initial "V" cut, cutting throught the cartilage mentioned before.

Here is the chicken after running your thumbs along the keel bone.

Next, just remove keel bone by pulling it up and out of the chicken. It should release fairly easily. There isn't much holding it in there anymore. Discard keel bone, or store with backbone and the bag of innards that comes with the chicken for making stock later.

And that's it! Flat as a pancake. Well, not quite, but a heck of a lot flatter than it was.

Now season her up get your ass out there to grill that bird!
