Heat the coconut oil in a large pot over medium to medium-low heat. Add the cumin seeds and toast for about 1 minute, stirring frequently. Next, add the ginger and garlic and sauté for another minute.
Transfer the rinsed millet to the pot. Stir to coat the millet with the oil. Next, add the coriander and salt and stir everything together. Pour the broth and water into the pot.
Cover the pot with the lid, increase the heat to medium-high and bring the liquids to boil.
Uncover the pot and reduce the heat to low. Mix in the pumpkin puree. Cover the pot and let the porridge simmer for 15 minutes.
Give the porridge a stir to ensure that it doesn’t scorch at the bottom of the pot. Cover the pot and cook for 15 minutes more.
The porridge might look runny when you first uncover the pot. Give everything a stir and the porridge should look thicker. If it still looks watery, cook the porridge on high heat another 5 minutes. Then, let the porridge cool, uncovered, for 10 minutes. The porridge thickens as it cools.
Serve the millet porridge in bowls. Enjoy it with chili oil, chili flakes, and sliced scallions, if you like.
