If you're tired of the rut of spatchcock chickens, drumsticks, thighs, etc., this should be a great diversion for you. The crusted chicken is great in and of itself, but the mustard sauce adds a nice ting to it.
A key ingredient is Pommery Mustard. It may be the most expensive mustard in the world. I think it's a lot like Dijon, and I suspect the sauce would be equally as good with Dijon. I paid $22 at Sur La Table for 17 oz. of Pommery.
I found the recipe at this site.
I can't wait to try the mustard on a hot dog.
