I just learned how to truss a chicken. I admit that I have never trussed a chicken until about 5 minutes ago, and I had to look it up on the internet. Trussing seems like a skill that all home cooks should know and sadly, I was lacking that skill. But now? NOW I can truss. I might practice on the dogs.
I decided to make Thomas Keller's roasted chicken after Adam Roberts' glowing review, but I subbed sweet potatoes and parsnips for rutabagas and leeks. My local grocery gets a F+ for not having rutabagas and leeks. http://www.amateurgourmet.com/2010/01/thomas_kellers.html#more
Here's the video I used to learn how to truss: https://www.youtube.com/watch?v=wXbYuPxC0es
