3 tablespoons butter
3 tablespoons sugar
1/3 cup dry white wine
1/3 cup orange juice
2 tablespoons raspberry vinegar
1 1/4 cups frozen blackberries, thawed
1 1/4 cups canned beef broth
1/2 cup canned low-salt chicken broth
2 tablespoons Cognac or brandy
1 tablespoon pure maple syrup
Melt 2 tablespoons butter in heavy large nonstick skillet over medium-high heat. Add sugar; stir until sugar dissolves and mixture turns deep amber color, about 5 minutes. Add wine, orange juice and vinegar (mixture will bubble vigorously) and bring to boil, stirring to dissolve caramel. Add 1 1/4 cups berries and both broths and boil until sauce thickens and is reduced to about 1 cup, stirring occasionally, about 25 minutes. Strain sauce through sieve into heavy small saucepan, pressing on berries with back of spoon. Mix in Cognac and maple syrup.
