Polish barszcz soup is a clear beet broth, tangy, sweet and earthy, with a hint of wild mushrooms and garlic. Traditionally served at Christmas with Polish uszka dumplings, this easy soup is ready in just over an hour!
Prepare mushrooms: Place the dried mushrooms (if using) in cold water and rub briefly with your fingertips to remove any grit. Drain, rinse and set aside.
Prepare beets: Peel then rinse the beets. Halve or quarter (larger) beets and place in a large pot.
Combine ingredients: Add the onion, garlic, celery root, parsley root, allspice berries, black peppercorns, salt and mushrooms (if using). Pour in the water and cover.
Cook barszcz : Bring to the boil, then lower the heat and simmer for 50 minutes. Remove from the heat.
Add flavour: Using a slotted spoon remove all the vegetables and spices from the pot (or strain the soup). Add the zakwas (if using), pickled beet brine, mushroom water (if using, add about ¾ cup/180ml) and butter. Taste, adjust the flavour if needed then serve with uszka dumplings.
Notes
*Buy a jar of pickled beets and use just the brine. See substitutions in Ingredients in the post.
**Zakwas is fermented beet brine (made without vinegar), sold in Polish stores, usually in bottles. See Ingredients for alternatives.
***Use either dried porcini/mixed mushrooms or about ¾ cup/180ml mushroom water (used for making mushroom uszka dumplings).
Add the beet brine and mushroom water after you've cooked the soup.
Adjust the amount of zakwas and pickled beet brine to your preference.
You can cook this dish up to 3 days ahead (and keep refrigerated).
Serve hot. If the soup gets cold reheat it but do not let it boil.
Yields 6-8 servings.
Freeze for up to 3 months.
Use rubber gloves when handling the beets.
