squash/pumpkin help needed...

Feeling slightly adventurous I bought this squash? pumpkin? of a kind that I've never eaten before. I don't know what it's called, because they were just labeled "miscellaneous squashes/pumpkins" (in German both are the same word) and there were a variety of them in the same bin, all for the same price. The one I got is quite small and white, and now I wonder what the best way to prepare it is. (I'm sure I could browse wikipedia for squash/pumpkin to identify it, and then google the name for recipes, but I'm lazy...)
