Caldo verde is Portuguese for "green broth". It is a popular soup in Portuguese cuisine.
The basic traditional ingredients for caldo verde are potatoes, kale or collard greens, olive oil and salt. Additionally garlic or onion may be added. Some recipes add meat, such as ham hocks. The soup is usually accompanied by slices of chouriço or linguiça which are boiled separately, the sausage is then added to the soup just before serving with Portuguese bread for dipping.
In Portugal, caldo verde is typically consumed during celebrations, such as weddings and birthdays or for popular celebrations. For example, the St. John festival in Porto. It is sometimes consumed before a main course meal or as a late supper.
Caldo verde originated from the Minho Province in northern Portugal. Today, it is a traditional national favorite that has spread across the nation and abroad, especially to places where a large community of Portuguese immigrants have settled such as Brazil, Massachusetts, New Jersey and Rhode Island.
