Salmon gravlax, the cured raw salmon dish originating from Scandinavia, has become beloved worldwide for its delicate texture and flavor. However, like any perishable food, proper storage is key to keeping gravlax safe and optimizing its shelf life.
In this comprehensive guide, we’ll explore the secrets to maximizing the longevity of gravlax, from the curing process to optimal storage methods. Read on for pro tips on identifying signs of spoilage, creative serving ideas, and more to help you get the most out of this luxurious ingredient.
Gravlax begins its journey as fresh, sushi-grade salmon filets which are coated in a dry cure mixture of salt, sugar, and spices. This curing process typically takes 2-5 days, during which time the fish is refrigerated while the cure penetrates the flesh.
The salt in the cure draws moisture out of the salmon, creating an environment inhospitable to bacteria. Meanwhile, the sugar balances the saltiness and adds subtle sweetness. Aromatic spices like dill, juniper, and black pepper infuse the gravlax with delicate flavor.
Once cured, the fish is briefly rinsed, patted dry, and sliced thinly. The result is a velvety textured, profoundly flavored salmon perfect for serving raw on bagels, incorporating into salads or sushi rolls, and beyond.
Optimal Fridge Life for Freshly Cured Gravlax
When handled and stored properly, freshly cured gravlax will keep refrigerated for 3-5 days after opening. The cure provides some protection against spoilage, but gravlax is still a raw product requiring diligent storage practices.
For best quality, keep gravlax well-wrapped in plastic wrap or in an airtight container. Store at 40°F/4°C or below and keep away from foods with strong odors, as gravlax can absorb nearby smells. Once opened, use within 3-5 days for peak flavor and texture.
Freezing Extends the Life of Gravlax for Months
Fortunately, gravlax takes exceptionally well to freezing. Properly frozen gravlax keeps its quality for up to 6 months.
To freeze, first divide gravlax into portion sizes. Wrap the pieces tightly in plastic wrap, then seal in freezer bags or airtight containers, eliminating air exposure. Label each package with the date before freezing.
Maintain a constant freezer temperature of 0°F/-18°C or below. At this temperature, gravlax remains frozen solid, preserving texture and preventing freezer burn.
When ready to thaw, leave gravlax overnight in the refrigerator This slower thaw protects the delicate cured fish Once thawed, use within 3-5 days.
How to Spot Spoilage in Gravlax
With vigilance and proper storage, gravlax can be safely enjoyed for its intended shelf life. However, it’s vital to watch for the following signs of spoilage:
-
Change in color – Fresh gravlax ranges from vibrant pink to orange hues. Dull, brownish or gray patches indicate spoilage.
-
Slimy texture – The cured fish should feel smooth and silky, never sticky or tacky. Sliminess means spoilage bacteria are present.
-
Off odors – Gravlax naturally smells mild, sweet, and oceanic. Strong “fishy” or ammonia odors signal the fish has turned.
-
Softness – As it spoils, gravlax loses firmness, becoming mushy. This change in texture signals it is no longer safe to eat.
If you observe any of the above, play it safe and discard the fish. Don’t risk foodborne illness.

Step 2: Two Different Flavours- How to Cure
For this step you will need a food processor of any kind, as long as its capable of blending blueberries and/or beetroot. At a push, if you dont have anything like that, you could mash the blueberries with a potato masher or a fork and grate the beets with a fine grater.
How to make the blueberry cure:
- Mix sugar and salt together, add grated zest.
- In a food processor, blend blueberries, alcohol and dill.
- Mix blueberry puree and sugar-salt mixture together.
- Thats it. Finished 😉
How to make the beetroot cure:
- Mix sugar and salt together, add grated zest.
- Peel beetroot (use gloves if possible and dont get any juice on your clothes).
- Blend beets with alcohol and dill.
- Mix beetroot puree with salt- sugar mixture.
- Finished.
Beetroot mixture is a bit thicker and more coarse than blueberry one, its to be expected. And each flavour has a different colour, beetroot is dark pinkish and blueberry is dark purple.
Find appropriate containers, small enough to keep salmon tight, but not too small, you dont want the salmon to be squashed or bend.
Line your containers with two layers of cling film, leave some of it hanging from the sides.
Pour a small amount of cure mix into the container, just enough to cover the bottom fully and place salmon on top. Pour the rest of the mixture on top of the fish.
Cover with cling film and seal tightly with a lid or more cling film.
Put the salmon in the fridge and leave it be. Curing process takes 48 hours.
- After 2 days, unwrap and rinse the cure from the fish.
- Use cold water, be quick and efficient.
- Pat the salmon dry with kitchen towels and place it back in the fridge. Ideally youd want to leave the salmon uncovered, but cover it with cling film if there is any chance your fridge has an odour or other strong smelling food that could potentially permeate the salmon.
