Known as agar or agar-agar, “kanten” is the Japanese name for the gelatinous substance made from seaweed. It is the freeze-dried and dehydrated form of congealed Tengusa, a type of red algae scientifically classified as Gelidium, and also a health food discovered 350 years ago in Japan. Today kanten agar comes in three forms: flakes, bars and powder, and various products are available at Asian stores and healthy markets.

Applications of Kanten

In Japan, many gelatinous sweets are made using kanten agar. It can be used as a substitute to gelatin, which is extracted from animal collagen, to make such desserts as jelly and pudding 100% vegan. Kanten agar does not have the same resilience or stickiness as gelatin, but is a strong coagulant that can solidify large quantities of liquid.

Kanten flakes make a great topping for soups and salads. Rich in dietary fibers, zero in calories and gluten free, kanten agar is more recognized as a healthy ingredient in Western countries. Kanten absorbs liquid and expands, so it also acts as an appetite suppressant.

It is perhaps good to know some cooking ideas and tips from a kanten manufacturer prior to using kanten.

The popular Mizu Shingen Mochi has been heavily replicated and recently introduced to the U.S. as “Raindrop Cake” by Darren Wong. The buzz spread to other countries and many eateries began to offer the Raindrop Cake so images of the kanten dessert are storming all over on social media. Many expect the raindrop cake to gain the status of “the dessert of 2016.”
