Warning
This soup is thickened with egg yolk, which must reach 74°C (165°F) to be safe. Warm the enriched broth gently, stirring constantly, and do not skip this step — undercooked egg poses a risk for pregnant women, young children, the elderly, and immunocompromised individuals.
- 1
Wash the veal and cut it into pieces. Place in a large pot with the cold water and bring to a simmer.
- 2
Add the parsley root, celery root, carrot, tomato, bell pepper, whole onion, salt, and pepper. Simmer gently, partially covered, for 1.5-2 hours, until the meat is tender.
Tip This soup was traditionally started in the morning to be ready by lunchtime. A long, gentle simmer is what gives the broth its depth — don't rush it. - 3
While the broth simmers, make the roux: heat the lard in a small pan, add the flour, and cook, stirring constantly, until golden. Remove from heat and stir in the sweet paprika.
- 4
Pour in the cup of cold water gradually, whisking constantly, to prevent lumps forming.
- 5
Once the meat is tender, remove it from the pot and set aside. Strain the broth through a fine sieve.
- 6
Return the strained broth to the pot, stir in the roux mixture, and simmer for a few minutes until slightly thickened.
- 7
In a separate bowl, whisk together the egg yolks and buttermilk.
- 8
Temper the egg-buttermilk mixture by slowly ladling in some of the hot broth while whisking constantly, until warmed through.
- 9
Pour the tempered mixture back into the pot with the rest of the broth. Warm gently over low heat, stirring constantly, until slightly thickened. Do not let it boil.
Tip Keeping the heat low and stirring constantly here brings the egg yolks to a safe temperature (74°C / 165°F) without curdling or scrambling them. - 10
Stir in the vinegar, tasting and adding more if you prefer a sharper finish.
- 11
Serve hot. The reserved veal can be added back into the soup, or served separately as a main course alongside the cooked vegetables.

Serving Suggestions
Serve the broth hot as a first course. The veal can be served alongside as a second course with the cooked root vegetables, in the traditional style, or added back into the soup for a heartier one-pot meal.
About This Recipe
This soup belongs to a family of broth-based dishes finished with an egg-and-soured-milk enrichment — a technique that adds body and a gentle tang without turning to cream or a heavy roux alone. Veal and a bundle of root vegetables simmer for hours into a clear, flavorful broth, which is then thickened lightly with a paprika roux before the egg and buttermilk mixture is folded in at the very end.
Traditionally, the broth was served as its own course, with the tender veal and vegetables set aside to be served separately — a structure worth keeping in mind if you’re planning the meal around it.
Why It Works
The long, gentle simmer draws flavor from both the meat and the root vegetables into the broth without breaking the veal down entirely, which is why patience matters more than heat here. The roux thickens the broth just enough to give it body, while the egg-and-buttermilk enrichment, added at the very end and warmed gently rather than boiled, is what gives the finished soup its characteristic tang and silky texture.
Modern Kitchen Tips
Don’t skip the tempering step, and don’t rush the final warming — a soup finished with egg yolk needs low, steady heat and constant stirring to thicken safely without scrambling. If the broth starts to look grainy, pull it off the heat immediately and keep whisking; a touch too much heat is the most common way this step goes wrong.

The Story Behind This Recipe
Historical Context
Early 20th century recipes for this soup were typically started in the morning so the veal would have several hours to simmer gently before being served at midday. Enriching a clear meat broth with egg yolk and soured milk, tempered together and warmed rather than boiled, was a common way to add body and a tangy finish to a broth-based soup. The meat itself was often reserved and served as a separate course, with the strained, enriched broth served first.
Modern Kitchen Adaptation
A phrase in the original noting the pot was set on the stove around ten in the morning has been read as a scheduling note for a midday meal, not as a literal ten-hour cooking time — the meat is tender well before that. A standard simmering time of 1.5-2 hours has been used instead. The composition of the root vegetable bundle, the pepper variety, the quantity of soured milk, and the roux seasoning were not fully specified in the original and have been estimated. Most importantly, the original does not clearly state whether the egg-and-buttermilk mixture is warmed again after the hot broth is poured over it — this step has been added and is not optional: the mixture must be returned to gentle heat and stirred constantly until it reaches a safe temperature, to avoid serving undercooked egg yolk.
