Potato soup with tarragon

To prepare a delicious potato soup with sour cream and tarragon, start by peeling the onion. Wash it well under a stream of cold water, then chop it finely so that it releases its flavors when sautéed. In a large pot, heat a little oil over medium heat and add the chopped onion. Sauté the onion, stirring occasionally, until it becomes translucent and starts to take on a light golden hue. This process will bring the flavors to life, creating an excellent flavor base for the soup.

Meanwhile, peel the potatoes and cut them into equal-sized cubes. This will ensure even cooking and a pleasant texture. Once the onion is ready, add the potatoes to the pot, mixing well to combine them with the sautéed onion. You can now add the dried vegetables, which will enhance the flavor of the soup. After adding all the ingredients, pour vegetable broth or water into the pot, enough to cover all the ingredients. Let the soup simmer over medium heat for about 10 minutes, until the potatoes become tender.

Meanwhile, prepare the sour cream mixture. In a bowl, combine the flour with the sour cream, mustard, and a little water, mixing well until you obtain a smooth paste. This combination will add a special creaminess to the soup. When the potatoes are almost done, take a ladle of hot soup from the pot and gradually add it to the bowl with the sour cream mixture, stirring constantly to avoid lumps. Once everything is well incorporated, pour the mixture back into the pot.

Let the soup simmer on low heat for 5 minutes, so the flavors can meld together. At this point, add salt, pepper to taste, and a handful of fresh tarragon, which will provide a refined and fresh flavor. You can also add a splash of vinegar, depending on your preferences, to give it a touch of acidity that will further enrich the flavor. After the soup has simmered and all the flavors have combined, take it off the heat and let it cool slightly before serving. Garnish each serving with fresh tarragon leaves and enjoy this comforting soup, perfect for a chilly day!
