From this issue of the Ascidian News comes word of something….well….awesome.
Tunicate Whiskey.
To wit, hollow out one Halocynthia roretzi. Fill tunic with Soju (korean whiskey). Drink.

For some reason, I think this would work really well with Laphroaig or other Islay malts. Or, perhaps, give that nice Islay character to something more generic – spice up your Johnny walker with a little Styela.
On second thought, a big Styela is about the size of a shot glass…
