Külmpressi

Külmpressi is a traditional Finnish method of preserving fish, particularly salmon and trout, using cold temperatures and salt. The technique dates back centuries and was originally developed as a way to store fish for long periods without refrigeration. The process involves packing fresh fish into wooden barrels or containers, layering them with salt and sometimes herbs or spices, and then sealing them tightly. The barrels are then submerged in cold water, such as a lake or river, where the surrounding temperature helps to slow down spoilage and bacterial growth, effectively preserving the fish for months or even years.

The name *külmpressi* comes from the Finnish words *kylmä*, meaning "cold," and *pressi*, meaning "press" or "compression." The method relies on the natural cold of the water to maintain the fish’s quality, distinguishing it from other preservation techniques like smoking or drying. Historically, külmpressi was a crucial food source for rural communities in Finland, especially during the long, harsh winters when fresh food was scarce.

Today, külmpressi remains a cultural practice and is still used by some traditional fishermen and food enthusiasts. While modern refrigeration has largely replaced the need for such methods, külmpressi is celebrated for its unique flavor and connection to Finnish heritage. The preserved fish retains a delicate, slightly salty taste and a firm texture, making it a prized delicacy in Finnish cuisine. It is often served as part of festive meals or enjoyed as a traditional snack, particularly during the winter season.
