The mineral, not the fruit. ;\)

And getting completely off topic...

I absolutely cannot stand the lemon & lime coke/diet coke mixes. I agree that a bit of fresh lemon or lime juice does add a nice component to coke/diet coke. But their canned stuff, blech. It's about the worst tasting chemical substitute for lemon/lime flavor ever. Tastes like pine-sol to me. Don't ask how I know what pine-sol tastes like.
