Suiton is a regional speciality of the Shinshuu area (Nagano prefecture). It's a miso or clear soup with soft wheat dumplings. Make it with plenty of vegetables, fish and so on, and it's a soup and a main dish all-in-one. It's very healthy too!
Make the suiton dumplings: Put the flour into a bowl.
Add the water to the bowl while mixing with chopsticks, watching the texture. The batter should be soft enough that it falls off the chopsticks when you life them up; this way the dumplings will be tender.
Cut the carrot and daikon radish into quarters, then slice into 1cm pieces.
Slice the sweet potato in the same way, and put in a bowl of water. Pour some boiling water over the aburaage to remove the excess oil, and cut up.
Put some dashi stock in a pan and bring to a boil. Add the carrot and daikon radish and simmer for 5 minutes.
Add the sweet potato, and simmer for 10 minutes while skimming off the scum.
When the vegetables are tender, add the flavoring ingredients.
When the soup comes to a boil again, add tablespoons of the suiton dumpling batter.
