A simple soup from Lithuania's mushroom country

Baravykų sriuba is exactly what the name says: porcini mushroom soup. In Lithuania, and especially in the heavily forested region of Dzūkija, mushroom picking is still a big part of local food culture. Porcini, known in Lithuanian as baravykai, are among the most prized mushrooms gathered in the forests.

The soup does not need much decoration. Good mushrooms already bring most of the flavor. Potatoes, carrots and onion make it filling, while sour cream and fresh dill finish the broth without hiding the taste of the porcini.

Fresh or dried porcini

If you have fresh baravykai, clean off the forest debris and trim away any damaged parts. You do not need to soak them in water, but there is no reason to panic if they need a quick rinse. Just wash them briefly when necessary and dry them well before cooking.

Dried porcini work very well too and are especially useful outside mushroom season. Soak them in warm water until they become soft and flexible. Depending on how thick and dry they are, this usually takes around 30 to 60 minutes.

Do not throw away the soaking liquid. It contains plenty of mushroom flavor. Pour it carefully through a fine sieve or cloth so any grit stays behind, then use it as part of the liquid for the soup.

Cooking the soup

Start with the onion and carrot in butter. You only want them soft, not deeply browned. Then add the porcini. Fresh mushrooms will release moisture as they heat; let some of that liquid cook away before adding the soup liquid.

Potatoes go in next and cook directly in the broth until tender. Water works for a simple version, while a mild chicken or vegetable stock gives the soup a little more body. If you are using dried mushrooms, add their strained soaking liquid as well.

Finishing with sour cream

Sour cream is a natural finish for this kind of Lithuanian mushroom soup. Do not drop a lump of very cold sour cream straight into vigorously boiling soup. Mix it first with a ladle or two of hot broth, then stir that mixture back into the pot.

Fresh dill goes in near the end. Add black pepper and check the salt only after everything has cooked together. The finished soup should still taste first of mushrooms, not of seasoning.

Why Dzūkija fits this recipe

Dzūkija in southern Lithuania is strongly associated with mushroom gathering. Its forests provide porcini and many other edible mushrooms, and local mushroom traditions include soups, stews, dumpling fillings, drying, pickling and preserving for winter.

There is no single official Dzūkian formula for baravykų sriuba. Families cook mushroom soup in different ways, and recipes can include fresh or dried mushrooms, different stocks, barley, bacon, cream or other herbs. This version keeps to a simple combination of porcini, vegetables, potatoes, sour cream and dill that fits comfortably within Lithuanian home cooking.

Expert tips:

Use the porcini soaking liquid

The water used to soak dried porcini contains plenty of mushroom flavor. Strain it carefully and use it in the soup instead of throwing it away.

Do not drown fresh mushrooms in water

Brush or wipe fresh porcini first. If they are still dirty, a quick rinse is fine, but do not leave them soaking in water.

Butter works especially well here

Butter gives the onion and mushrooms a rich flavor that suits this simple soup, but it is not required for the mushrooms to release their aroma.

Temper the sour cream

Mix the sour cream with some hot broth before adding it to the pot. This makes it less likely to separate when it hits the hot soup.

Storage:

How to store

Cool the soup and transfer it to a covered container in the refrigerator.

Shelf life

Eat refrigerated soup within 3 days. Reheat it gently over low heat rather than boiling it hard.

Freezing instructions

The complete soup is not ideal for freezing because potatoes and sour cream can change texture after thawing. For a freezer batch, freeze the mushroom and vegetable base before adding the potatoes and sour cream.

Ingredients

Substitutions for ingredients:

  • Fresh Porcini - Use dried porcini. Around 50 g of dried porcini is enough for this amount of soup and gives a strong mushroom flavor.
  • Porcini - Other edible wild mushrooms can be used, but the result should then be described more generally as Lithuanian mushroom soup rather than specifically baravykų sriuba.
  • Sour Cream - Use heavy cream for a milder version, although sour cream gives the soup a more characteristic tang.
  • Fresh Dill - Fresh parsley can be used if necessary, although dill fits this Lithuanian-style version particularly well.

Preparation

1. Prepare the mushrooms

If using fresh porcini, brush or wipe away loose dirt, trim the bases of the stems and cut the mushrooms into thick pieces. If they are particularly dirty, rinse them briefly and dry them well. If using dried porcini, soak them in warm water for about 30 to 60 minutes until soft.

2. Save the mushroom liquid

If you are using dried mushrooms, lift them out of the soaking water and chop them roughly. Strain the soaking liquid through a fine sieve, coffee filter or clean cloth to remove any grit and keep it for the soup.

3. Sauté the vegetables

Melt the butter in a large pot over medium heat. Add the chopped onion and carrots and cook for about 6 to 8 minutes until the onion is soft. Do not let it brown heavily.

4. Cook the mushrooms

Add the porcini and cook with the vegetables for about 5 to 10 minutes. Fresh mushrooms will release some liquid. Let part of it evaporate while stirring occasionally.

5. Simmer the soup

Pour in the water or stock. If using dried porcini, include the strained mushroom soaking liquid as part of the total liquid. Add the potatoes and a small amount of salt. Bring to a boil, reduce the heat and simmer gently for about 15 minutes, or until the potatoes and carrots are tender.

6. Temper the sour cream

Put the sour cream in a bowl and stir in one or two ladles of hot soup until smooth. Pour this mixture slowly back into the pot while stirring.

7. Finish with dill

Add the chopped dill and freshly ground black pepper. Heat gently for another minute or two without vigorously boiling the soup. Taste and add more salt if needed.

8. Serve

Serve the soup hot. Add a little extra dill or a spoonful of sour cream to each bowl if you like.

Frequently Asked Questions (FAQ):

What does Baravykų Sriuba mean?

Baravykų sriuba simply means porcini mushroom soup in Lithuanian. Baravykai are porcini or boletus mushrooms, while sriuba means soup.

Is Baravykų Sriuba traditional in Lithuania?

Mushroom soups are well established in Lithuanian home cooking. They are especially appropriate to Dzūkija, a heavily forested region with a particularly strong mushroom-foraging tradition.

Is this specifically a Dzūkija recipe?

The soup is not exclusive to Dzūkija, but the region is strongly associated with mushroom gathering and mushroom dishes. This simple porcini soup fits that regional cooking tradition well.

Can I use dried porcini instead of fresh ones?

Yes. Dried porcini are commonly used in mushroom soups. Soak them until soft and use the carefully strained soaking liquid in the soup.

How long should dried porcini soak?

About 30 to 60 minutes is usually enough, although very dry or thick pieces may need longer.

Should I wash fresh porcini?

Remove loose dirt with a brush or cloth first. A quick rinse is fine when necessary, but avoid leaving fresh mushrooms soaking in water.

Does Lithuanian porcini soup contain sour cream?

Sour cream is a common addition to Lithuanian mushroom soups, although recipes vary between households. Some versions use cream or are served without dairy.

Can I use vegetable stock instead of chicken stock?

Yes. Water, mild vegetable stock or chicken stock can all be used. Keep the broth mild so it does not overpower the porcini.

Can I make the soup with other wild mushrooms?

Yes, but if porcini are no longer the main mushroom it is more accurate to call it grybų sriuba, meaning mushroom soup, rather than baravykų sriuba.
