Agar (or Agar Agar), sometimes referred to as kanten, is a gelling agent coming from a South East Asian seaweed. It is used for scientific purposes (in biology for instance), as a filler in paper sizing fabric and as a clarifying agent in brewing.gar is the perfect substitute to traditional gelatin.

Agar has no taste, no odor and no color, which makes it pretty convenient to use.
