Instructions

1. 1

   Rinse the cleaned, parboiled tripe under cold running water for 3 minutes, then drain it well. This first rinse keeps the ciorbă clean-tasting while preserving the character of the beef tripe.

2. 2

   Put the marrow bones, beef shank, water, onion, carrot chunks, parsley root, celeriac, bay leaves, peppercorns, and 16 g of the salt into a large stockpot. Bring slowly to a gentle simmer, skim the foam carefully for 15 minutes, then keep the broth at a barely bubbling simmer for 2 hours and 30 minutes.

3. 3

   Add the rinsed tripe to the pot and continue simmering for 45 to 60 minutes, until the tripe is tender but still pleasantly springy. Do not boil hard, because aggressive boiling clouds the broth and can make the tripe rubbery.

4. 4

   Lift out the tripe and beef shank, then strain the broth through a fine sieve into a clean pot. Discard the bones, onion, roots, bay leaves, and peppercorns, and measure about 2.6 l of broth for the finished ciorbă.

5. 5

   Slice the tripe into thin strips about 6 cm long and shred the tender beef shank into bite-size pieces. Return both meats to the strained broth and simmer gently for 15 minutes so the textures settle into the soup.

6. 6

   Heat the sunflower oil in a small pan over medium-low heat and cook the finely grated carrot for 6 minutes, stirring often. Strain the orange oil into the soup and press the carrot lightly, then discard the carrot pulp for a classic golden ciorbă color.

7. 7

   Crush the garlic with the remaining 6 g salt until it forms a paste, then stir in 40 ml of the vinegar and 120 ml of hot broth. Let it stand for 5 minutes, strain it, and add the fragrant garlic liquid to the pot.

8. 8

   Whisk the sour cream and egg yolks in a large bowl until completely smooth. Slowly whisk in 600 ml of hot broth, one ladle at a time, to temper the mixture and prevent the smântână from curdling.

9. 9

   Turn the heat under the soup to low and stir the tempered sour cream mixture back into the pot in a thin stream. Keep the soup below a simmer for 5 minutes, because boiling after the liaison is added can split the creamy broth.

10. 10

    Stir in the remaining 40 ml vinegar, taste, and adjust only if the soup needs sharper acidity. Serve hot with pickled hot peppers, extra sour cream, and vinegar at the table so each person can season their bowl in the Romanian style.
