Orange Sorbet

In a small saucepan, combine 1/4 cup orange juice and sugar. Bring to a boil, and cook, stirring, until sugar dissolves, about 1 minute. In a shallow 2-quart dish, combine mixture with remaining orange juice. Transfer to the freezer.

Freeze until solid, 2 to 2 1/2 hours. With a fork, break into large pieces; working in batches, transfer to a food processor, and process until smooth. Keep covered in the freezer until ready to serve. Soften at room temperature 5 to 10 minutes before serving.
