Ciorbă rădăuțeană comes from Rădăuți, a town in the historical region of Bucovina in northeastern Romania. The soup is a relatively modern dish, attributed to local cook Cornelia Dumitrescu, who developed a chicken version with a rich, tangy character. Its name identifies its place of origin rather than a single unchanging formula. Contemporary recipes vary in the chicken pieces, vegetables, proportion of sour cream, and choice of acid. This home version uses bone-in chicken thighs to build a savory broth, familiar root vegetables, garlic, white-wine vinegar, and a tempered sour-cream-and-yolk mixture. It makes a substantial pot for six servings.
The soup’s defining texture comes from the liaison of cultured sour cream and egg yolks. The mixture is whisked separately, warmed gradually with ladlefuls of hot broth, and stirred back into the pot. This tempering step narrows the temperature gap so the dairy and yolks blend into the soup instead of forming cold streaks. Gentle heat after the mixture returns helps the egg component cook while keeping the broth smooth. Avoid a rolling boil at this stage: a vigorous boil can make the creamy finish separate. The method depends on controlling heat, not adding flour to conceal a broken texture.
Chicken thighs bring bones and connective tissue to the broth, while their meat stays moist enough to pull into strips after simmering. Start the chicken in cold water and bring it up slowly; skim the surface as foam appears. Onion, carrot, celeriac, parsnip, parsley root and green pepper add a mild vegetable base without turning the soup into a vegetable purée. The vegetables are simmered until tender, then the chicken is removed and shredded. Keep the carrot in the finished soup for visible color and texture. Straining the broth removes peppercorns and any loose foam or vegetable fragments before the creamy mixture is added.
Garlic and vinegar give the soup its characteristic savory-sour balance. Crush the garlic finely so it disperses through the broth rather than leaving harsh pieces in individual spoonfuls. White-wine vinegar is the measured acid in this recipe; stir it in near the end and taste the broth before serving. The amount makes a noticeable but restrained tang that supports the sour cream. Do not add all the vinegar to the cream-and-yolk bowl before tempering, because its sharpness is easier to judge once the full pot is assembled. Fresh parsley adds a green, herbal note at the finish.
Use a steady simmer rather than a hard boil while the chicken and vegetables cook. Gentle bubbles help keep the broth clearer and give the roots time to soften. Bone-in pieces vary in size, so verify the thickest piece of chicken with a food thermometer; poultry should reach 74 °C (165 °F). The vegetables should be tender when pierced, not collapsing. Lift the solids out with a slotted spoon or pour the broth through a fine sieve. Let the chicken cool just enough to handle, remove and discard the bones, then pull the meat into bite-size strands. Take care to keep raw-chicken utensils and cutting surfaces separate from the cooked ingredients.
When tempering the dairy mixture, whisk the egg yolks and sour cream until even. Slowly add several ladlefuls of hot broth while whisking continuously. This gradually warms the yolks and loosens the sour cream before the mixture goes into the pot. Lower the heat, pour the tempered liaison back in a thin stream, and stir as it disperses. Heat the soup gently until the egg mixture reaches at least 71.1 °C (160 °F), checking the liquid with a thermometer and stirring so the temperature is even. Do not let it boil. Return the chicken and carrot to the pot, then add crushed garlic, vinegar and parsley. Serve as soon as the soup is hot and smooth.
Ciorbă rădăuțeană is filling enough to serve as a meal, with the chicken and root vegetables in each bowl. The creamy broth should still pour easily; it is not a thick sauce. The sourness should brighten the chicken and dairy without masking them, and the garlic should be present but not dominate. Add parsley at the end for a fresh aroma. If setting out accompaniments, offer them separately so each diner can adjust the bowl without changing the base recipe. The soup’s Bucovina identity remains in its named origin and its chicken, sour-cream, egg and garlic profile, even as home cooks make small adjustments to vegetables and acidity.
Cool leftovers promptly and refrigerate them within two hours. Store the soup covered at 4 °C (40 °F) or colder and use within three to four days. Because the broth contains sour cream and egg, it can thicken or separate slightly after chilling; stir as it reheats. Warm portions in a saucepan over moderate heat, stirring often, and verify that leftovers reach 74 °C (165 °F). Avoid a hard boil during reheating to protect the texture. If the soup thickens, loosen it with a small splash of water or unsalted stock and stir until smooth. Do not leave the pot sitting at room temperature for a prolonged serving period.
