Candy or drink?
Either way, I've ordered some food grade ammonium chloride from Ebay and used it.
Or you can just get this from Amazon.
This one from Amazon is really good, extra salty. Ships from Amazon so you'll have it by the weekend.

I thought i would hate these with a passion because its basically black licorice on steroids, but i love them.
