Cook quinoa: In a large pot with a lid, warm the coconut oil over medium heat. Add the onion and cook, stirring often, about 5 minutes. Add the ginger, turmeric, curry powder and cardamom and stir, about 30 seconds. Pour in the coconut milk, water, rinsed quinoa and raisins. Bring the mixture to a boil, then cover and reduce heat to a simmer. Cook for 15 minutes, then remove the pot from heat and let it rest for 5 minutes.
