Gizmodo House update…
Made it to the semifinals. Still crossing my fingers. :p
Here’s the Flickr Photo Stream, if you guys are interested in taking a look.
It was made of:
Angel food cake (I wanted an artificially organic look, like critters from the old super mario games;
A whole pound of marshmellows (Melted down with sugar to make most of the surfaces)
Purple Tentacle was made of gumpaste. It’s a mixture of sugar, dextrose, cornstarch, and syrup. It’s basically a lump of sugar.
Whipped icing. Basically heavy cream and stabilizer, with various colors.
I’ll give the lowdown on "how it’s made" - including "making of" photos, almost every step - when the contest is over.
