Having two friends who are excellent cooks over to dinner Saturday, and the main dish will be a roasted duck.
I'd like to do something other than cherry sauce to go with it. The only barrier is that one of the guests is allergic to mustard (and fish too, but that's a moot point in this context). Otherwise, anything goes.
Your sauce suggestions will lead me to my sides. Have at it, because I get my best ideas here!
