Japanese Mizugashi Water Sweets and Kanten Seasonal Jelly Culture

Ingredients

• For the mizu yokan
• 4 g Powdered kanten (agar), dissolved in cold water before heating
• 500 ml Water
• 200 g Smooth anko (sweet red bean paste), added when liquid has cooled to 50 °C
• 1 tbsp Caster sugar
• 2 tbsp Fresh yuzu juice, summer variation; strained
• 1 pinch Fine salt
• For the kuromitsu
• 100 g Okinawan kokutō (raw black sugar), broken into pieces; not brown sugar
• 60 ml Water
• For the anmitsu assembly
• 2 g Powdered kanten (agar), for plain kanten cubes; dissolved in cold water before heating
• 300 ml Water, for plain kanten cubes
• 80 g Smooth anko (sweet red bean paste), portioned for each bowl
• 100 g Seasonal fresh fruit, white peach in summer, persimmon in autumn; sliced or diced
• 8 Shiratama mochi balls, prepared separately from glutinous rice flour and water

Method

1. 1
   Combine powdered kanten with 500 ml cold water in a saucepan. Stir to disperse fully before applying heat. Bring to the boil over medium heat, stirring continuously, and hold at a gentle boil for one minute. The liquid is ready when it is completely clear and no granules remain visible.
2. 2
   Remove the pan from heat. Allow the kanten liquid to cool, stirring occasionally, until it reaches 50 °C — confirmed by touch on the exterior of the pan, which should feel warm but no longer scalding. At this temperature, stir in the 200 g smooth anko and the sugar until fully incorporated. If anko is added to liquid that is still very hot, it disperses rather than suspends. This step decides the dish: the ratio of 2–2.5 g kanten to 500 ml liquid, held to, produces the barely-set, silky mizu yokan consistency; exceeding 4 g produces a firm sliceable bar. Add yuzu juice and salt, stir once more.
3. 3
   Pour the mixture into a dampened mould. Leave at room temperature for 20 minutes until the surface is set and no longer shimmers when the mould is tilted — kanten sets at approximately 38 °C without refrigeration. Transfer to the refrigerator until fully chilled and firm to a light press of one finger.
4. 4
   For the plain kanten cubes used in anmitsu, repeat the dissolution and boiling process with 2 g kanten powder and 300 ml cold water. Pour into a separate dampened flat container, cool at room temperature, then refrigerate. Once set, cut into 1.5 cm cubes. The cubes should hold their shape cleanly at the cut edge and appear translucent.
5. 5
   Prepare the kuromitsu: combine kokutō pieces with 60 ml water in a small saucepan. Dissolve over low heat without boiling hard, then simmer gently until slightly thickened — the syrup should coat the back of a spoon with a thin, even film. Commercial brown sugar syrup lacks the molasses complexity of kokutō and is not an equivalent. Pour into a small pitcher and cool.
6. 6
   Unmould the mizu yokan and slice into 1.5 cm portions with a dampened knife. The slice should shimmer at the cut face and hold its form while yielding immediately when a spoon edge is pressed against it.
7. 7
   Assemble the anmitsu: arrange kanten cubes in the base of each glass bowl or lacquer box. Place a portion of anko to one side, add the seasonal fruit, then the shiratama mochi balls. Serve with the kuromitsu in a separate small pitcher alongside — the addition of syrup is made by each diner at the table. Self-directed sweetness is a structural element of the dish, not an afterthought.
