Yokan (Japanese jelly candy) is a tasty jelly sweet made of red bean paste, sugar and agar. This little treat has a firm texture and is formed into convenient rectangular blocks and pieces. The two major types of yokan include mizu (water) yokan and neri (paste) yokan. 

Neri yokan is relatively firmer, thanks to a higher concentration of kanten, or agar powder. The texture is also a bit thicker and heavier. 

‘Mizu’ means ‘water’ in Japanese and this particular type is made using more water than usual. Mizu yokan is more popular among people as a Japanese summer snack because it’s lighter and often served chilled.

Though it doesn’t look as interesting and colorful as the western style jellies, it's absolutely an amazing treat when it comes to traditional Japanese sweets, or wagashi. Japanese people love it with matcha (Japanese green tea), as the sweetness of this red bean jelly compliments the bitterness of the tea.

The History Behind Yokan 

Yokan is originally a Chinese jelly and was made using gelatin made from boiling sheep meat. It was brought to Japan during the Kamakura-Muromachi period, between 1185-1573, by a Buddhist monk who was studying in China. Because Buddhism forbids killing, they replaced the animal-based gelatin with wheat flour and azuki beans (red beans). Later, agar was introduced to the recipe, making it plant-based and vegetarian or vegan-friendly.

How to Make Mizu Yokan

As we talked about earlier, mizu yokan is made using red bean paste, agar, sugar, and, most importantly, water. The red bean paste can be used as a smooth paste (tsubuan) or as a coarse paste (koshian). 

Although sweet red bean paste is used in traditional Japanese recipes, modern versions can substitute red bean paste with other ingredients, like white kidney beans, to add variation to this age-old dessert.

This also makes it easier to make with a trip to the grocery store. It’s typically molded in a rectangular block-shaped dessert, which is then sliced into smaller rectangles and chilled before it’s served.  

These days, mizu yokan comes in several flavors besides just the original flavor. Chestnuts, sweet potatoes, or even different types of fruits can also be added to any jelly recipe. Green tea is also a popular flavor among lovers of this sweet.

Ingredients Required for Yokan

  • 1 stick of dried kanten OR 2 tablespoon of kanten agar powder
  • Water for soaking the kanten
  • 1¼ cup of water
  • 1 cup of brown sugar
  • 1½ cup of sweet red bean paste

Step to Make Mizu Yokan

Step 1: Soak the kanten in a bowl for 1 hour or until soft. No need to soak if you are using kanten powder. 

Step 2: After the kanten softens, remove it from the water and squeeze it to remove excess water from the kanten. 

Step 3: Tear the kanten into small pieces

Step 4: Add the kanten pieces or kanten powder to a small saucepan with 1¼ cup of water and bring it to a boil. Whisk it constantly, so that it doesn’t mix too well with the water. Once it reaches a boil, the heat can be turned down to low. Keep whisking it on low heat until the kanten dissolves completely. 

Step 5: Once the kanten dissolves completely to the water, add sugar and mix well. 

Step 6: At this stage, mix the sweet red bean paste to the mixture. Stir continuously to make sure that the sweet red bean paste is diluted completely into the water. Keep simmering it until the mixture thickens. Once the mixture thickens, it can be removed from the heat.

Step 7: Now, pour the mixture into a nagashikan (a rectangular steal mold) or a regular plastic container that is shallow and rectangular so it can be removed easily. Let it cool down to room temperature until it solidifies and then refrigerate it. The mizu yokan should become firm when it’s chilled. 

Step 8: Cut the mizu yokan into small blocks and serve it chilled.
