Sauce

• 1 tablespoon unsalted butter
• 1 cup corn kernels
• 1 teaspoon chopped shallot
• 1 cup white wine
• 4 tablespoons cold unsalted butter, cut into 4 pieces
• 3 tablespoons ketchup

For the sauce: In a saucepan, heat the butter over medium heat. Add the corn and cook until softened, about two minutes. Add the shallot and white wine. Bring to a boil, reduce the heat, and simmer until the liquid is reduced by half, about 10 minutes. Let cool slightly and put in blender; purée until smooth. Add the cold butter, one piece at time, until incorporated. Strain the sauce back into the saucepan and keep warm. Just before serving, stir in the ketchup

Assembly: Prepare a barbecue grill. When hot, brush off the excess dry cure from the duck breasts and place the breasts on the grill. Cook until still pink inside, 5 to 7 minutes per side. Cut diagonally into thin slices and arrange on a plate. Spoon the corn sauce over the open portion of the plate and top with chopped chives.
