Mizu Yokan is a delicious sweet wagashi made with red bean paste, agar, and sugar. It is usually sold in blocks, but it is eaten in slices. There are two main types of ykan – neri ykan and mizu ykan. Niri ykan is sweeter than neri ykan, and it is eaten in the summer. It is best when made with a bit more water, as the fruit is very sweet.

Ingredients:
- 300g red bean paste (anko)
- 150g sugar
- 600ml water
- 10g agar-agar powder
- A pinch of salt
- 1 tsp vanilla extract (optional)
Instructions:
- Prepare Your Steamer:
- Fill the bottom of a steamer with water and bring it to a boil. Place a heat-resistant dish or Mizu Yokan mold in the steamer. Ensure that the dish or mold fits comfortably and has a lid.
- Combine Sugar and Agar-Agar:
- In a separate saucepan, combine the agar-agar powder, sugar, and a pinch of salt. Mix well.
- Add Water and Dissolve:
- Pour the 600ml of water into the saucepan with the sugar and agar-agar mixture. Heat the mixture over medium heat while stirring continuously. Allow it to come to a gentle boil. Let it simmer for about 2-3 minutes, or until the agar-agar and sugar are completely dissolved.
- Add Vanilla Extract (Optional):
- For added flavor, you can stir in a teaspoon of vanilla extract. This step is optional but enhances the taste.
- Incorporate Red Bean Paste:
- Take the red bean paste (anko) and stir it into the agar-agar mixture until it’s well combined. The anko should be evenly distributed.
- Pour into the Dish:
- Carefully pour the mixture into your heat-resistant dish or Mizu Yokan mold. Smooth the surface with a spatula.
- Steam the Mizu Yokan:
- Place the lid on the dish or mold and put it in the steamer. Steam it over high heat for about 30-40 minutes. The exact time may vary, so check it after 30 minutes. The Mizu Yokan should set and become firm.

Tips for making Mizu Yokan

Cooking Tips
- Quality of Red Bean Paste: Choose a good-quality red bean paste (anko) for your Mizu Yokan. You can make your own or buy it from a reputable source. The taste and texture of the anko greatly impact the final dessert.
- Agar-Agar Measurement: Be precise with your measurement of agar-agar. Too little can result in a dessert that doesn’t set properly, while too much can lead to a firmer texture than desired.
- Steamer Set-Up: Ensure your steamer is well-preheated and has a consistent steam flow. This ensures even cooking and a smooth texture.
- Mixing Red Bean Paste: When incorporating the red bean paste into the agar-agar mixture, mix thoroughly to achieve a uniform distribution. This ensures that every slice has the perfect balance of flavors.
- Cooling and Setting: Allow your Mizu Yokan to cool completely at room temperature before refrigerating it. This gradual cooling process helps in setting the dessert for the ideal texture.
Serving Suggestions

- Green Tea: Serve Mizu Yokan with a cup of Japanese green tea, such as matcha. The earthy flavors of green tea complement the sweetness of the dessert.
- Kuromitsu Syrup: Drizzle a bit of kuromitsu (black sugar syrup) over your Mizu Yokan. It adds a rich and slightly bitter contrast to the sweetness.
- Kinako Powder: Sprinkle some kinako (roasted soybean flour) on top. It provides a nutty and toasty flavor that pairs beautifully with the anko.
- Fresh Fruits: Garnish with fresh fruits like strawberries, raspberries, or orange segments. The fruity freshness balances the dessert’s richness.
- Chestnuts: For a traditional touch, add a piece of candied chestnut on the side. It’s a classic Mizu Yokan pairing.
- Ice Cream: If you enjoy experimentation, serve Mizu Yokan with a scoop of green tea ice cream. The temperature and flavor contrast can be delightful.
