Ciorbă Rădăuțeană

As tradition built it

About 2 hours; the breast simmers about 50 minutes.

Ingredients

The broth

• 800 g to 1 kg chicken breast, skin and bone on
• 3.5 litres cold water
• 1 tsp salt
• 100 g onions
• 250 g carrots
• 50 to 60 g celeriac
• 1 large bell pepper
• 6 to 8 black peppercorns

The liaison

• 4 fresh egg yolks
• 400 to 500 g sour cream (20 per cent)
• 50 g flour, or 30 g starch
• 4 cloves garlic, crushed
• 40 to 50 ml wine or apple vinegar
• to taste salt and black pepper
• 1 bunch parsley, chopped

To serve

• to serve hot chilli and toasted bread

Method

1. Cover the breast with the cold water in a 5 litre pot, add the salt, and bring it up over a medium-low heat, skimming 3 or 4 times until no more foam forms.
2. Keep one onion, one carrot and a slice of celeriac whole and dice the rest with the pepper. Add the whole vegetables and peppercorns.
3. Simmer about 50 minutes, until a fork goes easily into the thickest part, and no longer. Lift the breast out to cool.
4. Strain the broth, bring it back to the boil, add the diced vegetables and cook 20 to 25 minutes.
5. Skin and bone the breast and pull it into strips with two forks.
6. Turn the heat to a bare murmur. Whisk the yolks, sour cream and flour smooth, add the garlic, and warm it with hot broth a ladle at a time.
7. Pour it into the pot and stir 7 to 8 minutes on a very low heat, so it thickens without curdling.
8. Off the heat, season with salt, pepper and the vinegar, scatter with parsley, and serve hot with chilli and toast.

Notes

Invented in 1979 by the chef Cornelia Dumitrescu at Restaurantul Nord in Rădăuți, northern Moldavia, explicitly as a lighter, cheaper, faster alternative to the older ciorbă de burtă, its shredded chicken echoing tripe soup's own texture.

The recipe is Laura Laurențiu's, after Cornelia Dumitrescu's original; she does not say in so many words when the chicken goes back. Savori Urbane uses a whole chicken, discards most of the vegetables, adds meat and carrot after the liaison, and leaves the vinegar for each bowl. Neither uses dill.

What a modern chef changes

A sous vide poach and a proper fermented borș, per rung three

Rung 3

Method

1. Poach the chicken breast sous vide at a precise low temperature for a genuinely silkier texture than a rolling poach gives.
2. Build a proper borș, fermented from wheat bran and cornmeal over two to three days, per rung three, as the souring agent in place of a straight vinegar addition.
3. Clarify the finished broth with a gentle egg-white raft for real clarity rather than the traditional soup's characteristic cloudiness.
4. Finish with a dill oil rather than chopped dill stirred through, for colour and aroma without vegetal bulk.
