This is not what it sounds like (though chocolate noodles is on my long, loooong list of things to make). This folks, is molecular gastronomy.
Don't get scared off by the sound of it. It's basically playing with food and chemicals. Alternate titles are Modernist Cuisine, Avant-garde cuisine, and uh, Techno-emotional cuisine, apparently. So maybe those names make it sound scarier. But really all I did was melt down chocolate and agar agar (a natural thickening agent with a variety of uses including but not limited to vegetarian gelatin substitute, laxative and culture medium for microbiological work. So versatile!) and shoot it into a rubber tube. Impress your friends, humble your enemies!
