Ingredients
  • radishes, thinly sliced 300g
  • cucumber, thinly sliced 1 medium
  • kefir (plain, full-fat) 150ml
  • fresh dill, chopped 2 tbsp
  • spring onions, finely sliced 2
  • salt 1 tsp
  • white pepper 0.5 tsp
  • apple cider vinegar 1 tsp
  • sugar 0.5 tsp
Method
  1. 1

    Thinly slice the radishes and cucumber — a mandoline gives the most even results, but a sharp knife works fine. Aim for slices about 2mm thick.

  2. 2

    Place the sliced radishes and cucumber into a colander set over a bowl. Sprinkle over the salt, toss gently, and leave to sit for 5 minutes so the vegetables release their excess water.

  3. 3

    After 5 minutes, take small handfuls of the vegetables and squeeze them firmly over the sink to remove as much liquid as possible, then transfer to a clean mixing bowl.

  4. 4

    In a small bowl, whisk together the kefir, apple cider vinegar, sugar, and white pepper until smooth and slightly frothy.

  5. 5

    Pour the kefir dressing over the drained vegetables. Add the chopped fresh dill and spring onions, then toss everything together until evenly coated.

  6. 6

    Taste and adjust seasoning — a pinch more salt or a tiny extra splash of apple cider vinegar can brighten the whole thing depending on how sharp your kefir is.

  7. 7

    Serve immediately for the crispest texture, or refrigerate for up to 30 minutes before serving. Beyond that, the vegetables start to soften noticeably.

💡 Natali's tip: Salt the radishes and cucumber first, let them sit for five minutes, then squeeze out the liquid before adding the kefir — otherwise the dressing turns watery within minutes.

My mum made this every single Friday in spring, the moment the first bunches of radishes appeared at the market. She’d buy two or three bunches, the kind with the leaves still on and the roots still carrying a little dirt, and by lunchtime there’d be a bowl of this on the table. It sounds almost too simple to be worth writing about — sliced radishes, cucumber, kefir — but somehow it’s one of those things I crave more reliably than almost anything else when the weather turns warm.

Surówka, which just means “raw salad” in Polish, is the category rather than a single dish. Every Polish household has its own version, and the radish one is probably the most common spring expression of it. Traditionally it was made with soured cream or śmietana, which is richer and slightly less sharp than Western sour cream. I switched to kefir years ago partly out of habit and partly because the lighter, more acidic quality of kefir suits the peppery bite of radishes better than cream does. It also means the whole bowl sits at around 85 calories per serving, which is the kind of number that lets you eat it without doing any arithmetic in your head.

What makes it work as a diet-friendly snack rather than just a side dish is the combination of fibre from the raw vegetables and the protein and probiotics in the kefir. It keeps you fuller than its calorie count suggests it should, and the fermented base is genuinely good for gut health in a way that feels less like a claim on a packaging label and more like something you notice after eating it regularly for a few weeks. The sharp, almost radish-hot crunch against the cool, faintly sour cream of the kefir is one of my favourite contrasts in Polish food.

Serving Ideas & Variations

This works beautifully alongside open-faced rye bread with a thin scrape of butter, which is how my mum always served it. It also sits well next to grilled chicken or poached fish if you want to build it into a fuller meal rather than eat it as a standalone snack. Some people add a grated small apple for sweetness — I do this occasionally in late summer when the radishes are a little more bitter, and it works surprisingly well. A few finely chopped chives can stand in for the spring onions if that’s what you have, and a small clove of garlic pressed into the kefir dressing turns it into something altogether more assertive if that’s the direction you want to go.

Storage

The trick I learnt the hard way is that this salad does not keep well once dressed. The vegetables continue weeping liquid even after the initial salting step, and after a couple of hours in the fridge the whole thing becomes a puddle. If I’m making it ahead, I prep the vegetables, salt and squeeze them, and keep them in one container, then mix the kefir dressing separately and combine everything just before eating. That way it stays crisp for several days’ worth of quick lunches.

Frequently asked questions

How do I keep surówka from going watery?

Salt the cucumber and let it drain 10 minutes before mixing, and dress just before serving.

How long does it keep?

It's best fresh. Up to a day in the fridge, but expect some liquid at the bottom — give it a stir.

Can I make it vegan?

Yes — unsweetened plant kefir or plant yogurt works in the dressing.
