Sledz w Oleju (Polish Herrings)
About this recipe
Polish cooking is built around hearty cool-weather ingredients — cabbage, root vegetables, smoked sausage, mushrooms, sour cream — and the time-honoured patience of slow-cooked stews and braised pierogi fillings.
As a seafood dish, Sledz w Oleju (Polish Herrings) demands timing precision: the difference between perfect and overcooked is often less than 90 seconds, and the result of overshooting is a textural penalty there's no fixing.
The scaler above resizes every ingredient to the number of servings you actually want; Cook Mode walks you through the recipe one step at a time with hands-free timers.

Method
- Soak herring in cold water for at least 1 hour. If very salty, repeat, changing the water each time.
- Drain thoroughly and slice herring into bite-size pieces.
- Place in a jar large enough to accommodate the pieces and cover with oil, allspice, peppercorns, and bay leaf. Close the jar.
- Refrigerate for 2 to 3 days before eating. This will keep refrigerated up to 2 weeks.
- Serve with finely chopped onion or onion slices, lemon, and parsley or dill.
Cooking notes
Scaling works best when you weigh ingredients rather than measure by volume — small differences in packing can compound at higher multipliers.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Sledz w Oleju (Polish Herrings)
Sledz w Oleju (Polish Herrings) is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Seafood is the most scaling-sensitive protein because the overcooking window is narrow and the penalty is steep. Scale Sledz w Oleju (Polish Herrings) per piece if you can — cook three fillets in two batches rather than crowd the pan into one. Sauce-based seafood dishes scale linearly, but always taste before adding more salt: brininess from the seafood itself doesn't scale predictably.

Substitutions & make-ahead — Sledz w Oleju (Polish Herrings)
If you're cooking Sledz w Oleju (Polish Herrings) for a future meal (or doubling up for leftovers), here's how this dish handles storage, reheating, and the timing decisions most recipes don't spell out.
Make-ahead, storage, and reheating
Seafood is the worst-tempered category for make-ahead — texture and flavour both degrade quickly after cooking. Sledz w Oleju (Polish Herrings) should ideally be cooked the day it's served. If a make-ahead is unavoidable, prep components (the sauce, marinade, vegetables, garnishes) the day before and cook the fish or shellfish at the last moment. Cooked seafood develops a pronounced fishy off-flavour within 24 hours even when properly refrigerated.
