A Soup of Toasted Roots with Porcini Toasts
Dried porcini are expensive, but even a small handful added to a soup will bring with it a wave of smoky, almost beefy notes. A general instruction with parsnip soup is to prevent the vegetables coloring, presumably to keep the soup pale, but I suggest the opposite. You want the parsnips to cook to a gentle golden color before you add the stock; that way the soup will have a deeper flavor and a color reminiscent of heather honey.
