This recipe is from Laura Calder's show French Food at Home on the Canadian Food Network. I made this for Valentine's dinner, and it was yummy, even though I forgot the peppercorns .

Duck Breast with Green Peppercorn Sauce
1 duck breast
1 Tbsp Cognac
2 Tbsp red wine
2 tsp green peppercorns in brine, drained
1/2 cup veal stock
2 tsp butter
Heat the oven to 400°F/200°C. Score the duck breast and render the fat in a sauté pan. Pour off the fat, and transfer to the oven to finish, about 10 minutes. Remove the duck, and set aside to rest while you make the sauce.
Deglaze the sauté pan with the Cognac and wine and reduce by half. Add the peppercorns and veal stock and reduce by half again. Remove from the heat and whisk in the butter.
Carve the duck breast. Spoon over the sauce and serve.
Serves 2.
