CaviArt is a colorful line of "costume" caviar from Denmark. It is a vegetarian alternative to roe, made from sustainably harvested Nordic seaweed. It doesn't have the bold, briny flavor of the real thing but it is an acceptable stand-in and much less expensive. There's no refrigeration required and the colors don't bleed so it can be added to hot or cold dishes. It is popular in Scandinavia, but won't be available in America until spring.
