Leah and Orion in London made the London style recipe, with balsamic vinegar. A beauty!
On the other side of the pond, Samantha was substituting red wine vinegar for balsamic, tweaking the other ingredients and basting lovingly every 20 minutes. Here's her gorgeous bird!
Look for the original recipe, created in London, in a post on this blog in early September 2010.
Enjoy the cooking! Happy eating!
