Building off what Bently said, a couple of days ago I watched a Lidia Bastianich cooking show where she made a seafood and leek risotto that used saffron. She mentioned that saffron goes real well with seafood. She soaked some saffron in water, and then used the saffron and water as part of the liquid for the risotto. I have never used it personally, but thought I would share.
I believe it is used in paella as well.
