Zagorska juha
The green, hilly Zagorje north of Zagreb, in Croatia, is known for castles, vineyards and filling soups like this one, served in country inns before roast duck or as a meal on its own on chilly days. Potatoes and wild or chestnut mushrooms are simmered with paprika and marjoram, then finished with sour cream and a dash of vinegar, so the broth turns velvety with a gentle tang. Some versions add smoked bacon or sausage; this one is vegetarian, with dried porcini for a deep, woodsy flavour. Serve with dark bread. Where most people go wrong is boiling the soup after the sour cream goes in, which makes it curdle; warm it through and keep it below a simmer. Chef's tip: strain the porcini soaking liquid through a paper towel and add it to the pot; it is half the flavour.
