1 2-pound fully-cooked ham center slice -- cut 1-inch thick
1/3 cup water
1 tablespoon cornstarch
1/3 cup apricot preserves
2 tablespoons brown sugar
2 tablespoons dry red wine

Trim fat from edge of ham slice, if necessary. Place ham slice on rack in a shallow baking pan. Bake at 350F for 30 minutes.
Meanwhile, for the sauce, in a small saucepan combine water and cornstarch; stir in apricot preserves, brown sugar, wine, and lemon juice. Cook and stir over medium-low heat for 5-6 minutes or until thickened and bubbly. Stir in blueberries; cook and stir 2-3 minutes more. To serve, spoon sauce atop ham.
