4 slices pound cake frozen (4 x 2 1/2 x 3/4 -inch each)
1 11-ounce can mandarin orange segments drained
1/4 cup sugar
1/4 cup orange juice concentrate
1/4 cup butter cut in pieces
Place slices of cake on individual dessert plates. Return remaining pound cake to freezer. Arrange six orange segments on each slice; set aside until ready to serve.
In a small skillet, place sugar, orange juice and butter. Cook and stir over medium-low heat until butter melts. Simmer, without stirring, for 5 minutes or until mixture is golden and syrupy.
To serve, spoon 2 tablespoons of the warm sauce over each slice of cake, coating orange segments completely.
