Saving fresh herbs

I am constantly throwing away fresh herbs.... I use what I need then they wilt and die and get thrown in the trash.  I have a nice bunch of parsley that I knew would go bad while I was away, so I saved them in ice cubes (this is something I have read various times) then when it's time to use them in: sauce, soups, whatever, you throw the ice cube in!

cut up the herb

put them in an ice cube tray

fill with water

freeze, viola!
