Peel, pit and cut the peaches. Arrange the pieces in a pan with the wine and let cook for 20-25 minutes. Then crush and strain using a potato masher. Set aside until ready to serve.
In the meantime, in a microwavable dish, put the duck drumsticks and coat well with a mix of oil and tarragon. Cover the dish and microwave for 5 minutes at medium-high power.
Remove the drumsticks and serve with the peach sauce.
