It got real cold tonight so I decided to make a hearty soup. I found some lovely mustard greens and decided to make a soup with it, in place of the usual kale.
Caldo Verde - Portuguese Kale Soup
Serves 4 as a main course
1 large bunch of kale, cut into as fine chiffonade as you can manage
3 pounds small Yukon Gold potatoes, peeled and cut into 1-inch cubes
3 cloves garlic, minced
one handful scallions, sliced into thick rounds
8 ounces mild or spicy chouriço, sliced into thin rounds
2 tablespoons extra virgin olive oil
2 teaspoons kosher salt, plus more to taste (this will depend on the saltiness of your chouriço and broth)
64 ounces (8 cups) chicken broth
Toss the chouriço rounds into a large heavy pot (3+ quarts, preferably enamel) and turn burner heat to medium. Cook for 3-5 minutes, until they release a fair amount of their paprika-laced oil, but before they get really browned. Turn off the heat, remove the chouriço to a plate and pour off all but a tablespoon of the oil.
Return the burner heat to medium. Pour 2 tablespoons of olive oil into the pot with the chouriço oil and let it heat up for about 30 seconds. Add garlic and scallions and saute for 2 minutes, stirring often, until the garlic is slightly coloured. Do not let the garlic get too brown, or it will turn bitter. Add potatoes cubes and broth, and turn the heat to high. Cover and bring to a boil. As soon as it boils, turn the soup back to medium and cook, stirring occasionally, for 15-20 minutes, until the potatoes are tender. When the potatoes are done, use a potato masher (carefully, as the soup is still hot) to coarsely mash the potato cubes. This will give you a lovely thickened broth with a satisfying chunky texture. Add the kale ribbons and chouriço and gently simmer the soup for another few minutes, until the kale has softened slightly.
Let it rest, covered and off the heat, for 15 minutes, to let the flavours soften and meld. Serve with thick slices of good, crusty bread.
