A friend of mine gave a small bottle of this the other night and I have absolutely not idea what to do with it. 45% alcohol by volume, I'm assuming that it is like a spirit. Has anyone heard of anything like this. Do you mix it with anything, drink it straight or on the rocks, chilled or not....any help would be great.

There also looks to be something soft floating in it (like tiny pieces of paper...).
