Barszcz czerwony zabielany z Ziemak: beet soup with mashed potatoes

Barszcz czerwony zabielany z Ziemak is a traditional beet soup from Ziemaki, a village in northeastern Mazowieckie, Poland. It is associated with the Kurpie cultural region. Its defining bowl pairs tangy-sweet red barszcz made with fermented beet kvass and a separate portion of mashed potatoes.

The local method is deliberately simple: salt and sugar season the beet; wheat flour dissolved in cold water lightly thickens the soup; sour cream mixed with a whole beaten egg gives it a creamy finish. The egg-and-cream mixture is stirred in without a rolling boil so the soup stays smooth. This measured home version follows those defining details while gently heating the liaison to a safe temperature.

Serve the soup and potatoes as separate portions in the same wide bowl, rather than stirring the potatoes into the broth. The soup includes tender grated beetroot and has a light, slightly thick consistency. Only salt and sugar season it, keeping the fermented beet flavor at the center.

Tips for the best result

Tips for the best result

  • Use food-grade bottled fermented beet kvass and follow its label directions after opening.
  • Coarsely grate the beetroot so it cooks evenly and remains visible in the light-bodied soup.
  • Whisk the flour with cold water until completely smooth before adding it to the hot beet broth.
  • Temper the sour cream and beaten egg with hot soup a spoonful at a time to prevent curdling.
  • Use a thermometer to bring the finished egg-containing soup to at least 71°C, then remove it from the heat without boiling.
  • Keep the mashed potatoes in a distinct mound beside the soup in the bowl; that presentation is part of the dish.

Directions

  1. Cook the beetroot.Coarsely grate the peeled beetroot into a covered soup pot. Add 1.2 litres water, 4 g salt and the sugar. Bring to a boil, then cover and simmer until the beet is tender, about 25–30 minutes. Do not add other seasonings.

  2. Boil the potatoes.While the beet cooks, put the peeled potatoes in a separate pot with 2 litres water and 6 g salt. Bring to a boil and cook until a knife slides easily into the center, about 20–25 minutes. Drain, reserving a little of the hot cooking water, and keep the potatoes warm.

  3. Add the beet kvass.Stir the fermented beet kvass into the tender beet broth. Warm the soup back to a gentle simmer; avoid a hard boil so the fermented flavor stays bright. Taste for a balanced tangy-sweet beet flavor without adding spices.

  4. Thicken the soup.Whisk the flour with 80 ml cold water until smooth. Stir the slurry into the simmering soup and cook gently for 3–5 minutes, stirring, until lightly thickened and no raw-flour taste remains.

  5. Mash the potatoes separately.Drain the potatoes and mash them coarsely with only enough reserved hot cooking water to make a fluffy mash. Keep them separate from the soup; do not stir them into the beet broth.

  6. Finish with sour cream and egg.Beat the whole egg in a small bowl and whisk in the sour cream. Slowly whisk several spoonfuls of hot soup into this mixture to temper it. Remove the pot from direct heat and stir in the liaison. Return to low heat, stirring constantly, until a thermometer reads at least 71°C. Do not let the soup boil.

  7. Serve.Ladle about 350 ml barszcz into each of four wide bowls and place a separate mound of mashed potato beside it. Serve promptly while hot.

Serving, storage and reheating: Serve in a single wide bowl with the creamy beet soup and mashed potato as separate portions. Keep the seasoning restrained: salt and sugar in the soup let the sour beet kvass remain noticeable.

Serving, storage and reheating: Refrigerate leftovers in shallow containers within 2 hours at or below 4°C. Use within 2 days. Reheat gently to 74°C, stirring so the soup warms evenly; avoid boiling after reheating to protect its creamy texture. Do not leave the soup at room temperature for more than 2 hours, or more than 1 hour above 32°C.

Serving, storage and reheating: You can boil and mash the potatoes shortly before serving. The beet soup base can be made ahead through the flour-thickening step and refrigerated promptly. Reheat it until hot, then prepare and temper the sour-cream-and-egg liaison just before serving; gently bring the finished soup to 71°C without boiling.
