Ken of Onlyknives blog has just posted a how-to guide on making your own Jar Jar Binks out of jicama:
Jar Jar Binks was easily the worst thing about The Phantom Menace. If I could create a scrumptious salad out of him and serve him up with a tasty crostini, perhaps I might have my revenge.
Jicama proved to be just the right medium for my sculpture — it’s a tuberous root vegetable that is perfect for food carvings. It’s crisp, cuts easily and doesn’t dry out quickly. Jicama doesn’t taste like much but readily absorbs the juices and flavors of a marinade or sauce.
