Kanten is a flavourless dried seaweed available in blocks, strands or powdered form, which acts as a gelling agent. It is an ideal gelatin substitute for vegetarians. Delicious jellies can be made using fruit juice or milk and are popular in Japan as a healthy treat. High in fibre, kanten is good for treating constipation and reducing cholesterol levels. Tokoroten, the natural gel form of kanten, is usually cut into thin strips and eaten cold with sweet or savoury dressings such as soy sauce and rice vinegar.
