"A simply seasoned pan-fried duck breast is served with a ruby red sauce made with red plums, strawberries and raspberries. Roasted potatoes sprinkled with fresh rosemary is a great side dish to serve alongside this duck."
Melt butter in a saucepan over medium heat. Add plums, strawberries, raspberries, honey, and cinnamon stick. Stir well and simmer until fruit is soft, about 7 minutes.
Score duck breast skin in a diamond pattern. Season with salt and pepper.
Heat a skillet over medium heat and cook duck until skin is browned, about 7 minutes. Turn over and cook until duck is medium rare, about 5 minutes more. Slice duck breast in half to check for doneness. Continue cooking, if necessary, until an instant-read thermometer inserted into the center reads at least 165 degrees F (74 degrees C) and breast is still pink in the center. Slice thinly and serve with the warm sauce ladled over top.
