The Ruby King of Polish Soups
Czerwony barszcz is the undisputed heavyweight champion of Polish broths, taking centre stage at the Wigilia (Christmas Eve) table. Deep, vibrant ruby red, inherently earthy, and perfectly balanced between sweet and sharp. The soul of this soup relies on zakwas—a traditional fermented beetroot elixir that provides its signature tang, complexity, and striking colour. This isn’t a quick weeknight throw-together; it’s an exercise in patience and precision. We build a deeply savoury, mushroom-fortified vegetable base first, then coax out the sweet earthiness of fresh beets before finishing with the sour punch of the ferment.
CHEF'S SECRET: The Golden Rule of Barszcz—once the zakwas and fresh beets are in the pot, you must absolutely never let it boil. A rolling boil will destroy the vibrant ruby colour, turning it a muddy, unappetising brown, and it will violently kill the delicate, complex acidity of the ferment. Treat it with respect; keep it at a gentle whisper of a simmer.

Building the Foundation
A true, clear barszcz (Barszcz Czysty) is an extraction. You aren't eating the vegetables or the mushrooms in the final bowl; you are ruthlessly pulling every ounce of flavour from them into the liquid. By starting with cold water and slowly bringing the root vegetables and dried porcini up to a simmer, we ensure maximum flavour transfer. The fresh beets go in later so they retain their colour, and the zakwas is the final conductor that ties the earthy, sweet, and savoury notes together into something completely restorative.
