You can use freshly-squeezed orange juice, but if you do, strain the juice. 

If you buy prepared orange juice, choose the "no pulp" variety, or else strain it. 

If you don't have a sorbet maker, pour the mixture into the bowl of a food processor (with the blade). Place in the freezer. Thirty minutes later, place the bowl on the machine and process for a few minutes. Repeat the process three times, returning the bowl to the freezer for 30 minutes between each operation. In this way, you'll achieve a nice smooth texture. For a more mousse-like consistency, you can blend in 2 egg whites at the end with the food processor, then freeze again.
