Chestnut zenzai

Put the red beans in a pot, add enough water to cover and let it soak for 30 minutes.

Place it on a heater and bring to a boil and wash it under running water to let the scum go away. Fill the pot with water again and simmer over low heat for about 3.5 hours.

Add about 1/3 of the total amount of sugar and simmer over a heat that does not boil. Add remaining sugar in 2-3 portions. After simmering for about 20 minutes, remove from the heat and pour into a bowl.

Topped with sweet chestnut stewed in sweet chestnuts, it's finished.
