I used onion as i didn't have shallots. Delicious!
It would be nice if, in the video related to this recipe, Lucinda would come back and finish cooking the duck breasts. I waited through several "how to" videos for that to happen but it never did.
I made this today. I used a mix of red wine vinegar and balsamic as I did not have sherry vinegar and I used an onion instead of shallot. My wife loved it. So did I. Easy recipe and very delicious. Thank you!
