For four mallard breasts:
Duck fat or canola oil
1/2 c. shallots, finely chopped
1/2 c. dried cherries, roughly chopped
1/3 - 1/2 c. duck or chicken stock
2 tsp. chopped thyme
1/3 c. port
juices from the resting ducks
1 TBL unsalted butter
salt/pepper
When you finish sautéing your duck breasts, set them aside, either tented or in a warming oven. Turn the burner down to low. You want a tablespoon or two of fat in the pan. If there is more than that, remove some, or if there is too much add a bit of duck fat or canola oil.
Add shallots to pan, stirring constantly so they don’t burn. Just when they start to brown, add the chopped cherries and stir. Turn the heat up to medium and add the stock. Let it reduce a bit, and then add the thyme. Cook for a minute, and then add the port. Let that reduce for a couple of minutes. You want it thickened but with enough liquid to spoon over each duck breast. Add the juices from the resting duck breasts. Add butter and swirl to mix it together. Add salt and pepper to taste. Plate the duck breasts and spoon a couple of tablespoons of sauce over each.
