Frequently Asked Questions

Can I Use Different Cuts Of Pork Instead Of Organ Meats?

Certainly. While organ meats lend the soup a distinctive flavor and texture, substituting with other cuts like pork shoulder, tenderloin, or ribs is perfectly acceptable. The soup will still retain its rich and hearty character.

Is There A Preferred Type Of Apple Cider Vinegar To Use?

It is best to utilize raw, unfiltered apple cider vinegar for its nuanced flavor. However, in the absence of this, any good quality apple cider vinegar or dry white wine should suffice.

How Important Is The Use Of Lard In The Recipe?

Lard imparts a unique flavor and richness to the soup. If unavailable, you can replace it with unsalted butter or a neutral cooking oil, but note that there might be a slight change in flavor profile.

Is There Any Specific Type Of Water Recommended For This Soup?

Filtered water is preferred as it ensures that the soup is free from any contaminants or off-flavors that might be present in tap water. It allows the pure flavors of the ingredients to shine through.

How Do I Know When The Meat Is Perfectly Tender?

The meat should be easy to pierce with a fork and should almost fall apart with slight pressure. It’s crucial not to overcook, as this can render the meat mushy. Monitoring during the 2-hour simmering period is advised.

  • Pig’s foot

  • Pork meat and organ meats

  • Cold filtered water

  • Bay leaf

  • Fresh thyme

  • Cumin seeds

  • Garlic

  • Lard

  • Onion

  • Unbleached white flour

  • Paprika

  • Apple cider vinegar or dry white wine

  • Sea salt and freshly ground black pepper

Step-By-Step Directions

  • Preparation Steps
    Gather all the ingredients. Ensure the pig’s foot and organ meats are cleaned and diced properly.
  • Cooking
    Take a large stockpot. Place the pig’s foot and organ meats inside. Pour in the cold filtered water, ensuring everything’s submerged.
    Set the stockpot on medium heat. As it starts to simmer, carefully spoon off any scum appearing on the top.
    To the pot, add the bay leaf, thyme sprigs, cumin seeds, and chopped garlic.
    Reduce the heat to its lowest setting. Cover the stockpot, letting the soup simmer gently for about 2 hours. Throughout this duration, skim off any scum as it forms. Ensure the bones remain submerged by occasionally adding water.
  • Blending
    In a medium skillet, melt the lard over medium heat. Once melted, add the chopped onion. Sauté them until they become translucent but ensure they don’t brown – roughly 5 minutes.
    To the onions, add the flour and paprika. Stir them together until they form a smooth paste. Let this cook, while constantly stirring, for about 1 minute.
    Gradually introduce a ladleful of the soup into the skillet. This will help thin out the paste. Stir it constantly to prevent any lumps from forming.
  • Final Touches
    Now, incorporate this onion-paste mixture back into the main soup pot. Stir and bring the soup to a boil.
    It’s time to remove and discard the pig’s foot and the bay leaf from the soup.
  • Serving
    Before serving, season the soup with apple cider vinegar or white wine, salt, and freshly ground black pepper to taste.
    Ladle the soup into individual bowls. As a finishing touch, garnish each bowl with fresh thyme leaves.


  • The quality of ingredients matters; opt for organic meats and fresh herbs whenever possible.
  • Adjust the soup’s tanginess by varying the amount of apple cider vinegar or white wine.
  • Traditional recipes may vary slightly across Slovenian households. Embrace personal touches!
  • For a smoother broth, strain after simmering.
  • Serve hot and pair with a crisp Slovenian wine for an authentic experience.
