How to Make It
In a large saucepan, heat the oil over moderately low heat. Add the onion and cook, stirring occasionally, until translucent, about 5 minutes. Stir in the garlic and jalapeño and cook, stirring, until fragrant, about 30 seconds.
Stir in the kale, sweet potatoes, broth, and salt and bring to a boil. Reduce the heat and simmer, partially covered, until the potatoes are tender, about 20 minutes. Add the coconut milk and just heat through.
Meanwhile, bring a medium pot of salted water to a boil. Stir in the rice and boil until just done, 10 to 12 minutes. Drain. Put a mound of rice in the center of each bowl. Ladle the soup around the rice.
Crinkly kale leaves are wonderfully sturdy and flavorful, making them especially well-suited to soups. Remove and discard the thick stems and then wash the leaves really well before adding them to a dish. The twists and turns of kale leaves are great places for dirt to hide.
