Great Caviar Tip
In January's Gourmet there's a blurb about a product called cavi art (there's a mid-case "." between cavi and art but I'm too lazy to figure out how to do that in html). It's made from seaweed so veg-friendly and color-fast so it doesn't bleed into creme fraiche or whatever. It's supposed to be avialable in the states this spring.
