If you buy the real vanilla beans and not just the extract, pat yourself on the back. You're cooking like a pro! But wait, just because they've been scraped clean doesn't mean they're rendered useless.
Rinse them off and let them dry. Then throw them in you sugar jar! Baked goods will have an extra boost with vanilla scented sugar- and the pods last a looooong time.
My friend throws whole vanilla beans in her hot tub, but personally, I'd rather have them flavor my coffee.
