Chop the onion and dill.
Heat the coconut (or olive) oil in a pan over medium heat, and sauté onion for about 5 minutes.
Add the grated squash and salt to the pot, stir for a couple minutes then add water. Bring to a boil, and simmer for 15 minutes.
In a small bowl combine the flour with the cooking cream, adding a splash of liquid from the squash soup.
Pour the mixture into the pot and stir until you get a thick, smooth and lump free consistency. Simmer for another 2-3 minutes before serving.
