Understanding the Basics of Salmon Curing
What is Curing?
Curing is a process that involves the application of salt, sugar, and sometimes other flavoring agents to fish or meat to draw out moisture, inhibit bacterial growth, and develop flavor. Unlike cooking, curing doesn't involve heat; instead, it relies on the osmotic process where salt and sugar penetrate the flesh, creating a dense, flavorful, and tender product.
Types of Curing
There are primarily two methods of curing salmon:
- Dry Curing: Applying a dry mixture of salt, sugar, and spices directly onto the fish's surface.
- Wet Curing (Brining): Submerging the fish in a seasoned saltwater solution, also known as a brine.
Each method has its unique characteristics and results in different textures and flavors.

Key Ingredients and Tools
Ingredients for Curing Salmon
The foundational ingredients for curing salmon include:
- Fresh Salmon: Ideally wild-caught and sushi-grade for safety and quality.
- Salt: Coarse sea salt or kosher salt for effective moisture extraction.
- Sugar: Granulated sugar, which balances the salt and adds subtle sweetness.
- Spices and Herbs (optional): Dill, black peppercorns, juniper berries, lemon zest, or chili flakes to enhance flavor.
- Additional flavorings (optional): Vodka, gin, or aquavit can be used to add depth.
Tools Needed
- Sharp filleting knife
- Non-reactive container (glass or ceramic)
- Plastic wrap or parchment paper
- Weight (such as a heavy pan or bricks)
- Baking rack or wire rack
- Refrigeration space
- Sharp slicing knife for serving

Preparing the Salmon for Curing
Selecting and Preparing the Fish
Choose high-quality, fresh salmon, preferably wild-caught, with vibrant color and firm flesh. Before curing:
- Remove any pin bones using tweezers.
- Pat dry with paper towels.
- Decide whether to cure fillets or the entire side.
Skin and Bone Considerations
- Skin-on fillets help hold the shape and add flavor; skinless fillets are also fine.
- Removing bones ensures a smooth eating experience.

Step-by-Step Guide to Curing Salmon
1. Prepare the Cure Mixture
Combine the dry ingredients based on your chosen recipe. A classic cure might include:
- 1 part salt
- 1 part sugar
- Optional herbs and spices in small quantities
For example:
- 1/4 cup sea salt
- 1/4 cup granulated sugar
- Fresh dill and black peppercorns, crushed
2. Apply the Cure
- Place a layer of the cure mixture in a non-reactive dish.
- Lay the salmon fillet skin-side down.
- Cover the flesh generously with the cure mixture, ensuring all surfaces are coated.
- For larger pieces, rub the cure into the flesh with your hands.
3. Wrap and Weigh Down
- Wrap the coated salmon tightly in plastic wrap or parchment paper.
- Place the wrapped fish in a shallow dish.
- Add a weight on top (a plate with cans or a heavy object) to encourage even pressing and moisture extraction.
4. Refrigerate and Cure
- Cure in the refrigerator for a period ranging from 24 to 72 hours depending on thickness and desired firmness.
- Turn the fish every 12 hours to ensure even curing and reapply the cure if necessary.
5. Check and Rinse
- After the curing time, remove the salmon from the fridge.
- Unwrap and gently rinse off excess salt and spices under cold water.
- Pat dry thoroughly with paper towels.
6. Rest and Slice
- For optimal flavor development, let the cured salmon rest uncovered in the fridge for a few hours.
- Slice thinly at a slight angle using a very sharp knife.
- Serve immediately or store in an airtight container.

Tips for Perfect Curing
- Use high-quality, fresh fish to ensure safety and flavor.
- Maintain consistent refrigeration temperature (32°F to 38°F).
- Adjust curing time based on thickness and desired firmness.
- Always slice against the grain for tender slices.

Safety Considerations
While curing significantly reduces bacteria, it does not eliminate all pathogens. Always:
- Use fresh, high-quality fish.
- Cure at proper refrigeration temperatures.
- Avoid curing fish that shows signs of spoilage.
- Consider freezing the fish beforehand if unsure about safety, especially when serving raw.
