Caldo Verde
Minho region, northern Portugal
Caldo verde — literally 'green broth' — is Portugal's most iconic soup: a smooth potato base into which thinly shredded kale or collard greens are stirred in the final minutes of cooking, along with slices of chouriço and a thread of olive oil. The soup originated in the Minho region of northern Portugal where the specific kale variety (couve galega) grows tall and large-leafed, perfect for the ultra-thin chiffonade that defines the dish. The potato base is cooked and blended until completely smooth before the greens are added — the colour contrast between the white base and the vivid green ribbons is visual as well as flavour logic, since the greens must retain their colour and slight bite from a brief final cook. The chouriço is briefly simmered in the soup to lend its paprika-rich fat to the broth, then removed, sliced, and returned one or two rounds per bowl.
