Preheat the oven to 425 degrees F. Spray a 9-by-13-inch baking pan with canola oil spray. Sprinkle the fish with the salt and place it in the pan.
Combine the coconut milk, cilantro, ginger, garam masala, garlic and jalapeno in a blender and pulse until fairly smooth. Pour the mixture over the fish. Bake until the fish is just opaque in the center, about 15 minutes. Garnish with more cilantro and serve with the rice.
