Pour soup into a large saucepan and set over high heat. Stir in 1 cup (250 mL) water, squash, cumin seeds and half of chipotle. Bring to a boil, stirring often. Then reduce heat to medium-low. Cover and simmer, stirring occasionally, until squash is tender, 10 to 15 min. Taste, and if you want it hotter, add more chipotle. Spoon into bowls or large mugs and add a little sour cream to each. Sprinkle with cilantro.
