I've long wanted to post a chicken trussing video because there are so many silly videos out there that make it seem incredibly complicated. Of the many good ways of trussing a chicken, Brian's method here is solid and simple. Brian of course is the co-author of Charcuterie and chef/owner of Forest and Cinco Lagos outside Detroit.
I must clarify something here—it was noted to me by Bob del Grosso, who documented it at the Culinary Institute of America—that the main reason you truss a chicken is to ensure a juicy breast. That's what the even cooking part means. If the chicken isn't trussed, hot air circulates in the bird's cavity and will overcook and dry out the breast before the legs and thighs are done. If you do not want to truss the chicken, please stuff the cavity with lemon and onion, which will provide some protections for the breast.
But you should truss your chicken. It tastes better. It looks better. And it's fun to truss. I recommend trussing chickens for the pleasure of it.
