Thai Red Curry Żurek
My mom saw me pour coconut milk into żurek and nearly called the Polish police. “Co ty robisz?!” — What are you doing?! — she said, with the specific horror that Polish mothers reserve for culinary sacrilege. Żurek is sacred. It’s Poland’s sour rye soup — fermented rye flour base, kielbasa, hard-boiled egg, served in a bread bowl. You don’t mess with żurek. Except I did.
Ingredients
- 1 cup żurek starter fermented rye flour — available at Polish delis, or make your own: rye flour + water, fermented 3-5 days
- 1 can coconut milk 400ml
- 2 tablespoons Thai red curry paste
- 4 cups chicken broth
- 1 Polish kielbasa, sliced
- 4 hard-boiled eggs, halved
- 1 stalk lemongrass, smashed optional but recommended
- 1 tablespoon fish sauce
- Juice of 1 lime
- Fresh cilantro and Thai basil
- Salt and white pepper
Method
Build the Base
-
In a large pot, heat a tablespoon of oil over medium heat. Add the curry paste and cook 1-2 minutes until fragrant and the oil begins to separate — the same “cracking” technique from Thai coconut curry. Add the coconut milk and stir until combined. Then add the chicken broth and bring to a simmer.
Add the Sour Element
-
This is where żurek enters. Stir in the fermented rye starter — slowly, tasting as you go. The sourness should be noticeable but balanced by the coconut milk’s richness. In traditional żurek, the sour base IS the soup. Here, it’s one layer among several — it adds tang and depth without dominating. If you’ve never tasted żurek starter, it’s similar to sourdough tang — acidic, complex, slightly funky.
Add Aromatics and Protein
-
Add the smashed lemongrass stalk (it infuses the broth — remove before serving), fish sauce, and sliced kielbasa. Simmer 10-15 minutes. The kielbasa heats through and its smokiness infuses the broth, creating an aroma that’s part Polish kitchen, part Thai restaurant. It smells like nothing else you’ve ever made, and that’s the point.
Finish and Serve
-
Remove from heat. Stir in lime juice. Ladle into bowls. Add halved hard-boiled eggs (the żurek tradition that survives the fusion), fresh cilantro, and Thai basil. The final soup is creamy-orange with white egg halves and green herbs floating on top. It’s visually beautiful and aromatically confusing in the best possible way.
Thai Red Curry Żurek — Spicy Coconut Sour Rye Soup
My mom saw me pour coconut milk into żurek and nearly called the Polish police. “Co ty robisz?!” — What are you doing?! — she said, with the specific horror that Polish mothers reserve for culinary sacrilege. Żurek is sacred. It’s Poland’s sour rye soup — fermented rye flour base, kielbasa, hard-boiled egg, served in a bread bowl. You don’t mess with żurek. Except I did.
Thai curry sour soup takes the tangy, fermented base of żurek and blends it with Thai red curry paste and coconut milk. It keeps the kielbasa (why would I remove kielbasa from anything?). It keeps the hard-boiled egg. It adds lemongrass, fish sauce, and lime. The result is the most experimental recipe on Polish Mom — a soup that’s simultaneously sour like żurek and creamy like Thai curry, with a warmth that’s part Polish, part Southeast Asian, and entirely unexpected.
Is it authentic Polish? Absolutely not. Is it authentic Thai? Even less so. Is it delicious? My mother — the same woman who nearly called the police — ate two bowls and asked when I was making it again. That’s the only review that matters.

The Most Experimental Recipe on Polish Mom
Every other fusion recipe on this blog has a natural bridge: sauerkraut ↔ kimchi, schabowy ↔ katsu, pierogi ↔ gyoza. This recipe’s bridge is more abstract: both żurek and Thai curry are sour, aromatic soups with rich protein additions. Żurek gets its sourness from fermented rye. Thai soups get theirs from lime and tamarind. Combining the two sour traditions creates a double-tang that sounds aggressive on paper but is beautifully balanced in the bowl. The coconut milk smooths everything, the curry paste adds warmth, and the kielbasa grounds the soup in something familiar enough that even my most sceptical family members finished their bowls.
Tips
💡 Pro Tips
✓ Add żurek starter gradually. Too much makes the soup aggressively sour. Start with 1/2 cup and taste before adding more.
✓ Coconut milk balances the sour. If the soup is too tangy, add more coconut milk. If it’s too rich, add more żurek starter. You’re balancing two opposing forces.
✓ Kielbasa is non-negotiable. It’s the Polish anchor. Without it, the soup loses its identity crisis, and the identity crisis is the whole point.
✓ Lemongrass is optional but transformative. It adds a citrusy fragrance that bridges the Polish and Thai elements.
How to Store
Fridge 4 days. The sourness intensifies overnight (same as regular żurek). Add fresh lime juice and herbs when reheating. Not freezer-friendly — the coconut milk separates. Best made fresh in small batches.
Frequently Asked Questions
Where do I get żurek starter?
Polish delis sell it in jars (look for “zakwas żurowy” or “żurek starter”). You can also make your own: mix 1/2 cup rye flour with 1 cup warm water, cover loosely, and let ferment at room temperature for 3-5 days until sour and bubbly. It’s essentially a rye sourdough starter — the same fermentation principle behind sourdough bread.
Variations
• Green curry version: Use green curry paste instead of red. Brighter, more herbaceous, and slightly spicier. The sour rye base handles both curry colours beautifully.
• With kopytka: Drop small kopytka into the soup instead of serving with bread. Polish potato dumplings in Thai-Polish fusion broth. The kopytka absorb the coconut-sour broth and become extraordinarily flavourful.
• Milder for kids: Use 1 tablespoon curry paste instead of 2, and add extra coconut milk. The sourness mellows with more coconut and the curry warmth becomes background rather than foreground. My younger kids eat the mild version — the kielbasa and egg are familiar enough to keep them comfortable.
Is this too weird?
It’s the most adventurous recipe on the blog, and I understand if it feels like a bridge too far. But here’s my pitch: if you love żurek and you love Thai curry, the combination is less strange than it sounds. The sour-creamy-savoury flavour space is one that both soups already occupy. The fusion just expands that space. Start with less żurek starter and more coconut milk if you’re cautious — you can always add more sourness. And the kielbasa-and-egg combo keeps one foot firmly in Poland, which makes the Thai elements feel less like a leap and more like a step.
