Instructions
Start by frying the chorizo slices in a large frying pan with a lid over medium heat. Cook until the chorizo begins to crisp up and releases its smoky, flavorful oil, which will form the base of the stew. Next, add the chopped onion to the pan and sauté for about 5 minutes until it starts to soften and turn translucent, infusing the dish with sweetness. Then, stir in the minced garlic and finely chopped parsley, cooking for an additional minute to release their fragrant aromas. Pour in the vegetable stock and tinned tomatoes, stirring gently to combine. Bring the mixture to a boil, then reduce the heat to low to maintain a gentle simmer. Add the butter beans and sherry vinegar, which brings a bright acidity to balance the richness. Let the stew simmer uncovered for 10 minutes, allowing the flavors to meld and the liquid to reduce slightly, thickening the broth into a delicious sauce. Scatter the clams evenly over the stew and cover the pan with a lid. Steam the clams for 2 to 4 minutes, shaking the pan occasionally to ensure even cooking. The clams are ready when they've all opened — discard any that remain closed. Before seasoning, taste the broth as the clams can be naturally salty. Adjust seasoning with care to avoid over-salting. Finally, sprinkle over additional chopped parsley for a fresh, vibrant finish. Serve the stew hot, accompanied by plenty of crusty bread to soak up the rich, savory juices. This is comfort food at its best, perfect for sharing with family and friends on a cozy evening.
