These peppers from New Mexico have a grassy aroma that stands out in a wonderful way next to the earthy flavor of freshwater fish.
If you can find a whole fish and you are comfortable using a fillet knife, a 3 1⁄2 to 4 lb fish will yield plenty of meat for the stew and enough scraps to make the stock. Don’t use the gills, guts, or scales in the stock, but if you have the liver, it will add richness. If you prefer, have the fish filleted for you and ask your fishmonger for the scraps.
In a blender or food processor, combine 1½ cups/ 40 g of the parsley leaves and 2 cups/480 ml of the stock and purée until smooth. Set aside.
In a large saucepan over medium-high heat, bring the remaining stock to a simmer. Heat a medium sauté pan over medium heat until a drop of water flicked on the surface sizzles gently on contact. Add the sunflower oil to the sauté pan and then immediately add the onions, garlic, mushrooms, fennel, and 1 tsp of the salt. Cook, stirring occasionally, until the vegetables begin to soften, about 10 minutes. Add the chile powder and stir until fragrant, about 1 minute. Transfer the cooked vegetables to the simmering stock along with the fish pieces, collard greens, fish sauce, anchovies, and remaining 2 tsp salt. Simmer until the fish is cooked and the collards are tender, about 5 minutes. Note that carp and catfish are more delicate than sturgeon. They will fall apart if cooked for more than 5 minutes or stirred too vigorously. Stir in the puréed parsley mixture and remove from the heat.
Ladle the stew into individual bowls. Tear the remaining parsley leaves directly into each serving. Add a squeeze of lemon juice to each bowl and garnish with green onions, parsley, and pepper. Leftover stew will keep in an airtight container in the refrigerator for up to 4 days.
