NBR: What is xx sugar?

RunningGal900

I have a recipe that calls for xx sugar. I have never seen that before. I was thinking maybe it is powdered sugar. Google didn't get me any great results. Thanks!

It might be hard to find. We have a few family recipes that call for it and it is not easy to find around here.
