Combine red wine, sugar, orange peel, and orange-flavored liqueur in a large saucepan.

Bring the mixture to a boil, then reduce to a simmer.

Simmer for 30 minutes over low heat until the liquid has reduced by half and becomes slightly syrupy.

Remove from heat and cool in the refrigerator.

Strain the sauce to remove the orange peel.

In a mixing bowl, combine sour cream with confectioners' sugar.

Take a large platter and spread the sweet sour cream on it.

Arrange the strawberries with the bottoms down in the sour cream.

Pour the chilled red wine sauce over the strawberries.

Dust the entire plate with confectioners' sugar.
