Kylmäsuolattu

Kylmäsuolattu is a Finnish term referring to a food preservation method, typically applied to fish. The process involves salting the fish at low temperatures. This technique aims to draw out moisture from the fish through osmosis, inhibiting the growth of spoilage microorganisms. The low temperature component is crucial as it slows down enzymatic activity within the fish and further reduces the risk of bacterial proliferation.

The specific temperature range for kylmäsuolattu can vary, but it generally falls below typical refrigeration temperatures, often closer to freezing point. This controlled environment is key to achieving the desired preservation while maintaining a desirable texture and flavor in the final product. The salt not only acts as a preservative but also contributes to the taste and firmness of the fish.

Commonly, this method is used for fatty fish such as herring and salmon. The resulting kylmäsuolattu product is often consumed as a delicacy and can be prepared in various ways, including as a part of salads, appetizers, or main courses. It is a traditional method of food preservation in Nordic countries, valued for its ability to extend the shelf life of perishable goods without requiring high heat or extensive processing. The exact salt concentration and curing time are adjusted based on the type of fish and desired outcome.
