Basil anyone?

I have learned that I have a green thumb for herbs. There are two big pots on my deck that are seriously flourishing. Can basil turn into a bush? Or a tree? Anyway, there's really not a lot I can do with basil- I know pesto and a good old tomato basil salad. But other than that I'm looking for new ideas. I guess the point of writing this is to prepare all visitors to my home that as a parting gift you will receive a bunch of fresh herbs that you can grind into pesto.
