Add the winter melon and 300 ml of water. Add the dashi stock and sugar and boil for 5-6 minutes over medium heat.
Add the soy sauce and salt (the winter melon should become transparent).
Pour in a katakuriko slurry to thicken and it's done (adjust the thickness to your preference).
Transfer to a serving dish and enjoy.
Add onions as a topping, if you like.
