Detailed instructions
Overall progress: 0% completed
Phase 1: Sautéing Mushrooms and Caraway – 10 min
Appliances: Stove
1. Melt 3 tbsp of unsalted butter in a 4-quart heavy-bottomed Dutch oven over medium-high heat (350 °F equivalent surface heat). Add 8 oz of sliced fresh wild mushrooms and 1 tsp of caraway seeds. Sauté for 8 to 10 minutes, stirring occasionally, until the mushrooms release their moisture and turn golden brown.
CP: Visual check point (VKB): Mushrooms are deeply caramelized and aromatic with no excess liquid in the pot.
Before moving to the next step:
Ensure the mushrooms are fully browned before adding potatoes to develop a rich umami base.
Phase 2: Simmering Potatoes – 15 min
Appliances: Stove
2. Add 1.5 lb of peeled and diced Russet potatoes and 4.5 cups of warm vegetable stock to the pot with the mushrooms. Season with 1.5 tsp of salt and 0.5 tsp of black pepper. Bring the mixture to a gentle boil, then reduce heat to medium-low, cover with a lid, and simmer for 15 minutes until the potato cubes are tender when pierced with a fork.
VKB: Potatoes yield easily to gentle pressure from a fork.
Before moving to the next step:
Check potato tenderness to ensure they are fully cooked before introducing the sour cream liaison.
Phase 3: Preparing the Sour Cream Liaison – 5 min
Appliances: None
3. In a medium mixing bowl, whisk together 1.25 cups of heavy sour cream and 3 tbsp of all-purpose flour until completely smooth and free of lumps. Ladle about 1/2 cup of the hot soup broth from the pot into the sour cream mixture while whisking vigorously to temper the dairy and prevent curdling.
VKB: Liaison is completely uniform and warm to the touch.
Before moving to the next step:
Ensure the tempered mixture is smooth before pouring it into the simmering pot.
Phase 4: Thickening and Seasoning – 5 min
Appliances: Stove
4. Pour the tempered sour cream mixture in a steady stream into the simmering soup while whisking constantly. Stir in 2 tbsp of distilled white vinegar and 0.75 cup of finely chopped fresh dill. Simmer gently over low heat for 5 minutes, stirring frequently, until the soup thickens into a velvety consistency.
VKB: Soup coats the back of a spoon and maintains a smooth, glossy appearance.
Before moving to the next step:
Keep the heat low so the sour cream does not separate or curdle.
Phase 5: Poaching the Eggs – 5 min
Appliances: Stove
5. While the soup simmers, bring a separate small pot of water with a splash of vinegar to a gentle simmer. Crack 6 large eggs individually into small cups, then slide them into the simmering water. Poach for 3 minutes until the whites are set and opaque while the yolks remain soft and runny. Remove with a slotted spoon.
VKB: Egg whites are firm on the outside while yolks yield softly to gentle touch.
Before moving to the next step:
Drain excess water from the poached eggs before placing them into the soup bowls.
Phase 6: Plating and Serving – 5 min
Appliances: None
6. Ladle the hot mushroom and potato soup into 6 warmed bowls. Carefully place one poached egg in the center of each bowl. Garnish with a pinch of freshly chopped dill and a crack of black pepper. Serve immediately while piping hot.
VKB: Poached egg rests proudly on top of the velvety soup, ready to release its yolk when cut.

WAGUU Pro level
- Pro standard: Verified recipe with precise ratios and visual checkpoints.
- Tip 1: For the ultimate authentic flavor, use a mix of foraged wild mushrooms such as porcini and chanterelles.
- Tip 2: Always temper the sour cream by adding warm broth gradually; pouring cold dairy directly into simmering soup causes unsightly curdling.
- Tip 3: Add a splash of fresh lemon juice right before serving to elevate the herbaceous notes of the dill.
- Tip 4: Poach the eggs in slightly vinegared water to help the egg whites coagulate quickly and maintain a neat shape.
Scientific background
The exceptional flavor profile of Kulajda relies on Maillard browning during the initial mushroom sauté, which creates complex savory compounds. The starch released from the Russet potatoes combines with the flour-thickened sour cream liaison via gelatinization and protein emulsification, resulting in a rich, stable suspension that coats the palate gracefully without feeling heavy.
Fine Dining – Professional techniques

- Texture contrasts: Combine the velvety smoothness of the velouté broth with tender potato cubes and the soft, yielding texture of the poached egg.
- Temperature contrast: Ensure the soup is piping hot while the poached egg is warm, delivering a pleasant thermal interplay on the tongue.
- Aromatic garnishes: Finish with finely chiffonaded fresh dill and freshly cracked black pepper just before presenting to the guest.

FAQ
Can I make Kulajda ahead of time?
Yes, you can prepare the soup base ahead and store it in the refrigerator. However, poach and add the eggs just before serving to maintain their ideal texture.
Why did my sour cream curdle in the soup?
Curdling happens when cold sour cream hits boiling liquid too quickly. Always temper the dairy with warm broth and keep the heat low when simmering.
What kind of mushrooms work best?
Wild mushrooms like porcini, chanterelles, or cremini provide the most authentic and robust flavor profile.
Is this soup vegetarian?
Yes, when prepared with vegetable stock, this recipe is fully vegetarian while remaining rich and satisfying.
WAGUU Petr advises: Cooking for 12 or more people?
12–16 people: Scale all ingredients exactly by doubling the quantities. Use a larger 8-quart stockpot to ensure even heat distribution and prevent overcrowding during the mushroom sautéing phase. • 20+ people: Divide the preparation into two separate pots to maintain precise temperature control during the sour cream liaison phase. Poach the eggs in batches just before service.
Sides and serving
- Artisan sourdough bread – Crusty and perfect for dipping into the velvety broth (not included in the recipe)
- Fresh cucumber salad – Lightly dressed with vinegar and sugar to complement the creamy soup (not included in the recipe)
Serving: Serve piping hot in deep bowls, ensuring each portion receives a generous share of wild mushrooms, potato cubes, and a whole poached egg resting on top.
Storage and reheating
Fridge: 3 days in an airtight container • Freezer: 2 months (freeze the soup base only without poached eggs) • Reheating: Reheat gently on the stovetop over low heat, stirring frequently. Do not boil vigorously to prevent the sour cream from separating.

Common mistakes
- Adding cold sour cream directly to boiling soup – Causes the dairy to curdle and separate; always temper the sour cream with warm broth first.
- Overcooking the potatoes – Results in a mushy texture; test the potato cubes at 15 minutes to ensure they remain tender-firm.
- Skipping the caraway seeds – Removes an essential aromatic backbone characteristic of traditional Bohemian soups.
- Overboiling after adding the liaison – High heat breaks down the emulsion; keep the soup at a gentle simmer after the sour cream is incorporated.
