This guide teaches you to transform frozen farm-raised salmon into tender, buttery sashimi using a saline solution to firm the texture and enhance flavor. The salt-brine method safely thaws the fillet while preventing mushiness.

In a large bowl, prepare a 3-4% saline solution by dissolving the salt in cold water.
Remove one frozen salmon fillet from its packaging.
Submerge the frozen salmon in the saline solution. If you are not placing the bowl in the refrigerator, add ice cubes to keep the water cold.
Let the salmon thaw and brine in the solution for about 30 minutes. For best results, do this in the refrigerator.
Remove the salmon from the brine and pat it completely dry with paper towels.
Place the dried salmon fillet in a zip-top bag, removing as much air as possible, and refrigerate for 5 hours to firm up the texture.
After 5 hours, remove the salmon from the bag and pat it dry one final time.
Using a very sharp knife, slice the salmon against the grain into sashimi-style pieces.
Serve immediately with your choice of dipping sauces, such as soy sauce with wasabi or cho-gochujang.
Store thawed, unsliced salmon in an airtight container on ice for up to 24 hours; slice only when ready to serve. Sashimi does not reheat well.

Farm-raised salmon works best for this method. Ensure it's labeled sashimi-safe or sushi-grade and has been properly frozen to kill parasites.
The saline thaw typically takes 2–4 hours depending on fillet thickness. Check progress every hour and adjust ice as needed.
Salt water firms the salmon's texture during thawing and seasons it subtly, resulting in a more cohesive, less mushy final product.
Cold water thawing without saline is faster (1–2 hours) but produces softer texture. The saline method trades time for superior bite and mouthfeel.
The fillet should be fully flexible and cool to the touch with no icy crystals inside. It should flake slightly when gently pressed.
