The Nightly Bowl: Sopas para a Alma
This doesn't require chicken stock or sautéed aromatics to church it up—true peasant ingenuity doesn't need fixing, working simply by boiling potatoes, onions, and a link of linguiça in plain water until they surrender to a wooden spoon. Let the starch and smoky pork fat create their own starchy broth as the fat renders, then add supermarket kale sliced thin as thread, boil it uncovered so it stays brilliantly green, and finish the glorious mess off the heat with a heavy pour of raw olive oil. Ladle it into a heavy bowl, watch the oil pool against the dark greens, and eat.
Ingredients
- Yukon Gold potatoes1 1/2 lb
- yellow onion1 large
- garlic3 large cloves
- water6 cup
- kosher salt1 1/2 tsp
- extra virgin olive oil1/4 cup
- Portuguese chouriço or smoked kielbasa6 oz
- collard greens or lacinato kale1/2 lb
Method
- 01
Build the broth from scratch.
In a large heavy-bottomed pot, combine the potato chunks, onion, garlic, and the whole unsliced sausage. Pour in the water, add the salt, and drizzle in exactly 1 tablespoon of the olive oil. Bring to a rolling boil over high heat, then reduce the heat to medium, cover, and let it simmer vigorously for 20 minutes until the potatoes are completely tender and falling apart.
- 02
Prepare the greens with a tight chiffonade.
While the soup simmers, stack 4 or 5 leaves flat, roll them up tightly lengthwise like a cigar, and use your sharpest chef's knife to slice them crosswise as thinly as humanly possible—you want delicate, hair-like ribbons.
- 03
Mash and emulsify the potatoes.
Carefully use tongs to remove the hot sausage from the pot and set it on a cutting board to cool slightly. Leave the pot on the heat. Using an immersion blender, blend the potatoes, onions, garlic, and cooking water directly in the pot until the broth is incredibly smooth, creamy, and velvety.
- 04
Boil the greens completely uncovered.
Bring the creamy potato broth back to a steady, rolling boil and drop in your shredded greens. Do not put the lid back on the pot. Boiling uncovered lets the natural plant acids escape, ensuring the soup stays a vibrant, beautiful green. Let the greens boil rapidly for 5 to 8 minutes, just until tender.
- 05
Finish with raw olive oil off the heat.
While the greens boil, slice the cooled sausage into thin coins. Once the greens are tender, turn off the heat completely. Stir the sliced sausage back in to warm through, then pour the remaining 3 tablespoons of olive oil directly into the hot soup with one gentle stir to preserve its rich, fruity aroma.
Notes
Choose the right sausage.
If you can't find Portuguese chouriço or linguiça, a firm, smoked Kielbasa or cured Spanish chorizo works perfectly. Never use raw Mexican chorizo, which will disintegrate and ruin the soup.
Serve with rustic bread.
Ladle the hot soup into deep bowls and serve immediately with hunks of crusty artisan bread or traditional Portuguese broa for dipping.
