Begin by sprinkling 4 g kanten agar powder and 3 tbsp sugar into a cold pan. Mix until combined.
Gradually add 500 ml cold water while gently whisking.
Place the pan on the stove and bring to a boil over a medium heat. Boil for 2 minutes and stir occasionally. Turn off the heat and fill a larger pan with cold water. Hold the smaller pan over the cold water and mix for a few minutes to cool slightly.
Pour the mixture into a 7 inch square container and cool for 10-15 minutes before chilling in the refrigerator for about 1 hour.
Kuromitsu Syrup
Add 50 g dark brown sugar, 50 g white sugar and 120 ml cold water to a cold pan. Mix well and then place the pan on the stove. Heat on low and continue to stir until the sugar has dissolved.
Once the mixture starts to bubble, stop mixing and continue to heat until slightly thickened (about 5-7 minutes). Tilt the pan occasionally to heat evenly. Remove the pan from the heat and leave to cool before transferring into a serving container.
Shiratama Dango
Start boiling a pot of water. While you wait, pour 65 g glutinous rice flour into a bowl and whisk while it's dry to aerate it. Measure out 60 ml water and add half of it to the bowl. Mix thoroughly.
Add the rest of the water little by little, kneading by hand each time until you can form a ball with a play dough-like texture. You might need to use a little less or more water than stated, adjust the amount according to the texture of the dough.
Divide the dough into 12 equal pieces (2 per portion) and once the pot of water is at a rolling boil, roll the pieces into balls and drop them straight into the water.
Each time you add a dango to the pot, gently roll it to stop it from sticking to the bottom of the pan. Boil until they all start to float, then set a timer for 2 minutes.
While the dango are boiling, prepare a bowl of ice cold water. When the 2 minute timer is up, transfer the dango the to ice cold water and leave to cool.
Assembly
Cut the kanten jelly into 2cm (approx 1 inch) cubes.
Divide them into serving bowls and top with a 50g scoop of red bean paste and two shiratama dango.
Arrange the fruits on top and add whipped cream or ice cream. Drizzle generously with kuromitsu syrup and enjoy!
