What is Kanten?

Kanten (寒天) is a semi-translucent gelling agent made by harvesting red seaweed, which is then boiled, hardened, and sun-dried. It is flavorless and retains its firm shape at room temperature. 

It is a great alternative to gelatin and is appropriate for vegetarians/vegans. Low in calories, it’s also high in dietary fiber, calcium, iron, and natural iodine. Hop over to my Kanten page to learn more about this ingredient used in traditional Japanese desserts and seaweed salads.

Ingredients You’ll Need for Kanten Jelly

  • kanten powder – also called agar powder; see below for substitutions
  • water
  • sugar – you can add more, to taste
Agar Powder in packages.

How to Make Kanten Jelly

Here’s a brief overview; see the written recipe below for the full instructions:

  1. Add water and kanten powder to a small saucepan.
  2. Whisk and boil on medium-high heat to dissolve the powder in the mixture.
  3. Add sugar and cook on low heat for 2 minutes.
  4. Pour into a baking dish. Cool, then refrigerate to set.
  5. Cut into cubes and serve.

Substitutes for Kanten Powder

Please note that each type of gelling agent produces a different texture, so the end product will be slightly different depending on the type you use. To set 2 cups (500 ml) of liquid, you will need:

  • 1 stick packet (4 g) kanten powder
  • 1 bar (8 g) kanten stick
  • 24 pieces (8 g) kanten threads
  • 4 tsp powdered gelatin or agar powder

To use kanten stick, rinse it carefully and break it into pieces to soak in water for 30 minutes. This will help dissolve the kanten faster. Squeeze the water out from the pieces and they are ready to use.

If you are using kanten stick: You will need to rinse it carefully and break it into pieces to soak them in water for 30 minutes. This will help dissolve kanten faster. Squeeze the water out from the pieces and they are ready to use.
If you want to use gelatin or agar: 1 tsp kanten powder = 2 tsp powder gelatin or agar
In order to set 1 cup (250 ml) of liquid, you will need:
  • Kanten powder = 1 tsp (2 g)
  • Kanten stick = ½ stick (4 g)
  • Kanten thread = 12 threads (4 g)
