Delia does a wonder recipe for Duck with Sour Cherries, These are sometimes called Bing Cherries, and are not easy to get......Sainsburys had them last time I looked.
score the skin, season and then sear them skin-side down, hot pan no oil butter, until they are bronzed. Drain off any fat during this phase. Then sear the meat side for 30secs.
and then into an oven at 220c for the following times
Rare - 10 minutes
Medium - 15 minutes
Well Done - 18 minutes
Plus (very important) let the meat rest for 10 minutes under some foil and a t-towel across it.
