Why this recipe works everything about caldo verde, the classic Portuguese soup of smoky sausage, potatoes, and sturdy greens, is hearty and satisfying. Its intentionally thin broth is usually made with just water, but for our version we wanted something with a little more body. We used chicken broth for deeper flavor, and also realized that we could nicely thicken the broth by pureeing some of the softened potatoes with a few tablespoons of olive oil. Using plenty of potatoes and garlicky chorizo turned this simple soup into a filling meal; we chose Yukon Golds because they held their shape better than russets. We prefer collard greens here for their delicate sweetness and meatier bite, but kale can be substituted. Serve this soup with hearty bread and a final drizzle of extra-virgin olive oil.
