This elegant soup is really just a simple purée of white beans, but top it with some earthy sautéed wild mushrooms and a dollop of herbed mascarpone cheese, and it becomes a refined first course. The trick to getting a smooth, silky texture is to purée the beans and vegetables with only a small amount of the cooking liquid first, and then to slowly pour in more liquid until you get a nice, creamy consistency.
