The Swissmar girouette says it was devised to shave and curl Tete de Moine, a fancy cheese from Switzerland that probably costs $100 pound, but you can also use it to make byooteeful ribbons of chocolate, or on any old cheese you can cram on its hand crank. Like for example the 1-pound cylinders of wax-wrapped Wisconsin cheddar my mama used to buy for $5.99. Sometimes I would sneak one out of the fridge and cut myself a fat disk for a snack. Sometimes I even remembered to peel the wax off before eating it.
Another thing about the girouette's intended cheese, Tete de Moine, is that Tete de Moine mean's Monk's Head in French. Now the thought of eating a monk's head by way of shaving it off layer by layer does not particularly appeal to me, but according to Wikipedia, this oxygenates the head's surface and brings out its aromas and flavors.
Anyway, if you're searching for a way to make chocolate and cheese look spiral-y and intricate and novel for a party, I would recommend Swissmar's girouette, paired with a big hunk of chocolate or a wheel of hard cheese. And if you are looking for a gift for a zombie, I would also recommend Swissmar's girouette, paired with a nice, ripe Tete de Moine.
The pictured girouette measures approximately 8-1/2" in diameter.
