📝 About This Recipe

Borș is the soul of Romanian sour soups, a vibrant, probiotic-rich liquid gold made from fermented wheat bran and cornmeal. This ancient recipe yields a tangy, slightly floral base that transforms ordinary broths into complex, revitalizing masterpieces. Unlike vinegar or lemon, Borș provides a nuanced acidity and deep nutritional profile that has been a staple of Eastern European hearths for centuries.

🥗 Ingredients

The Fermentation Base (Huște)

  • 500 grams Wheat bran (organic and coarse-ground is best)
  • 200 grams Cornmeal (preferably stone-ground)
  • 1 cup Huște (Starter) (sediment from a previous batch or a piece of sourdough bread)

Aromatics and Liquid

  • 4-5 liters Spring water (filtered, non-chlorinated)
  • 1 bunch Lovage (Leuștean) (fresh or dried; essential for authentic flavor)
  • 2-3 pieces Cherry tree twigs (optional, adds a subtle woody sweetness)
  • 1/2 piece Beetroot (small slice for a rosy hue)
  • 3-4 pieces Dill stalks (for depth of aroma)

👨‍🍳 Instructions

  1. 1

    Select a large 5-liter clay pot or glass jar. Ensure it is meticulously cleaned and scalded with boiling water to prevent unwanted bacterial growth.

  2. 2

    In a large bowl, mix the wheat bran and cornmeal. Add the 'huște' (starter) or the crumbled sourdough bread to the dry mixture.

  3. 3

    Add about 1 liter of lukewarm water to the bran mixture. Stir well with a long wooden spoon until it forms a consistent paste.

  4. 4

    In a separate pot, bring the remaining 3-4 liters of water to a boil, then let it cool until it is hot but not scalding (about 60°C/140°F).

  5. 5

    Slowly pour the hot water over the bran paste in the large jar, stirring constantly to avoid lumps.

  6. 6

    Add the lovage, dill stalks, cherry twigs, and the slice of beetroot. These aromatics will infuse the liquid as it ferments.

  7. 7

    Cover the jar with a clean linen cloth or cheesecloth secured with a rubber band. This allows the gases to escape while keeping dust out.

  8. 8

    Place the jar in a warm spot (near a radiator or in a sunny corner) for 24 to 48 hours. In colder climates, this may take up to 4 days.

  9. 9

    Twice a day, stir the mixture vigorously with a clean wooden spoon to aerate the ferment and encourage the yeast.

  10. 10

    Taste the liquid after 24 hours. It is ready when it is pleasantly tart, slightly fizzy, and has a clear golden-yellow color.

  11. 11

    Once fermented, strain the liquid through a fine-mesh sieve lined with cheesecloth into clean glass bottles.

  12. 12

    Save the sediment at the bottom (the new 'huște') in a small jar in the fridge to use as a starter for your next batch.

  13. 13

    Store the bottled Borș in the refrigerator. It will stay fresh and potent for up to 2 weeks.

💡 Chef's Tips

Always use non-chlorinated water, as chlorine can kill the beneficial bacteria needed for fermentation. If the mixture develops a fuzzy mold on top, discard it and start over; the smell should be sour but clean, never putrid. For a deeper flavor, use more lovage; it is the signature herb that gives Romanian soups their distinct identity. To speed up fermentation in winter, you can add a tablespoon of honey to the initial paste. When adding Borș to a soup, always boil it separately for 2 minutes first to 'clarify' it before pouring it into your main pot.

🍽️ Serving Suggestions

Use this liquid to sour a traditional Ciorbă de Perișoare (meatball soup) for an authentic Romanian Sunday dinner. Drink a small glass of cold, raw Borș in the morning as a probiotic tonic to aid digestion. Pair a Borș-based soup with a side of hot chili peppers and a dollop of cold smântână (sour cream). Serve alongside fresh crusty bread and a slice of red onion for a rustic, traditional experience. It works beautifully as a marinade for poultry, helping to tenderize the meat before roasting.
