How to make jelly using Agar Agar Powder


  • 2 tsp powdered (agar agar) (2 tsp= 4 g)
  • 2 cups water (2 cups = 500 ml)
  • 2 Tbsp granulated sugar (or more, optional)


  1. Gather all the ingredients.
  2. Add water and agar powder in a small saucepan.
  3. Whisk the mixture together and bring it to a hard boil on medium-high heat, being careful not to let the liquid boil over.
  4. After the mixture has boiled and agar powder is dissolved, add sugar and cook on low heat for 2 minutes. If you add sugar before boiling, agar powder may not be dissolved.
  5. Remove the saucepan from the stove and pour the mixture into an 8″ x 8″ (20 x 20 cm) baking dish. Allow it to cool and let the agar set in the refrigerator (about 20 minutes).
  6. Cut into ½” (1.5 cm) cubes and they are ready to serve. Keep the jelly in an air tight container in the refrigerator for up to 3 days.


Recipe Notes

Powdered agar agar:- Agar needs to be heated to dissolve properly. The powdered form of agar is easiest to measure and use; bars and flakes should be dissolved in water first. It sets in about an hour at room temperature (Source).

If you are using agar/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 agar/kanten faster. Squeeze the water out from the pieces and they are ready to use.

If you want to use gelatin: 1 tsp. agar/kanten powder = 1 tsp. powder gelatin

In order to set 1 cup (250 ml) of liquid, you will need:

Agar/Kanten powder = 1 tsp (2 g)

Agar/Kanten stick = ½ stick (4 g)

Kanten thread = 12 threads (4 g)

Agar flakes = 1 Tbsp (4 g)

Equipment you will need:

  • 8″ x 8″ (20 x 20 cm) baking dish

An 8″ x 8″ (20 x 20 cm) baking dish is a perfect size to cut agar-agar jelly into nice cubes but you can use other mold(s).
