Radziwiłłów Sorrel Soup (Barszcz szczawiowy z Radziwiłłowa)
Introduction: This Mazovian soup pairs bright, tangy sorrel with a light vegetable or chicken broth, a gentle sour-cream and buckwheat thickener, potatoes and a hard-cooked egg.
Barszcz szczawiowy z Radziwiłłowa is associated with Radziwiłłów Mazowiecki in the Mazowieckie region. Sour soups in the area were also called barszcz or borsc. The soup was prepared in several ways, from fresh sorrel in spring and summer or salted sorrel in winter.
The documented method combines chopped sorrel, softened briefly in water or butter, with a light broth. Sour cream and buckwheat flour give it a gentle body, while salt and pepper keep the flavour clear. Potatoes and hard-boiled eggs are among the recorded accompaniments; this measured home version serves both alongside the soup.
Keep the broth pale and loose, with visible leaves rather than a puree. Add the sorrel late, and temper the sour-cream mixture with hot broth so it blends smoothly without curdling.
