So, what exactly is gravlax, and how is it different from other salmon delights like lox or smoked salmon? Simply put, gravlax is salmon cured with a mix of salt, sugar, and fresh dill. The key difference lies in the method:
Gravlax: Cured (not smoked). It relies solely on the salt and sugar mixture to transform the fish.
Lox: Typically refers to salt-cured salmon, often with a brinier taste and softer texture. It's usually not smoked either.
Smoked Salmon: This is salmon that has been cured and then smoked, giving it a distinct smoky flavor and often a drier, flakier texture depending on whether it's cold or hot smoked.
The texture of perfect homemade gravlax should be silky-firm, translucent, and incredibly easy to slice into thin, delicate pieces. It’s a truly elegant way to enjoy fresh salmon fish, especially when you choose the best wild salmon to buy, like wild caught Alaskan sockeye salmon or other wild salmon fillets. Let's dive in!

Ingredients

• 1.5-2 lb fresh wild caught salmon fillet (center-cut, skin-on recommended for easier handling)
• 1/2 cup Kosher salt (Diamond Crystal recommended)
• 1/4 cup Granulated sugar
• 2 tablespoons freshly cracked black pepper
• 1 large bunch fresh dill, roughly chopped (about 1 cup packed)

Directions

1. Prep the Salmon:
   1. Carefully run your fingers along the flesh side of the fresh salmon fish fillet to feel for any small pin bones. Use a pair of tweezers or needle-nose pliers to gently pull out any bones you find.
   2. Pat the salmon fillet very dry with paper towels. This is crucial for the cure to work effectively and prevent a mushy texture.
2. Mix and Apply the Cure:
   1. In a small bowl, combine the Kosher salt, granulated sugar, and black pepper. Mix thoroughly.
   2. Lay about half of the chopped fresh dill evenly on the bottom of a baking dish or rimmed sheet pan that's just large enough to hold the salmon fillet.
   3. Place the wild salmon fillet, skin-side down, on top of the dill.
   4. Evenly coat the flesh side of the salmon with the salt-sugar-pepper mixture, pressing it gently to adhere. Ensure all surfaces are covered.
   5. Top the salmon with the remaining fresh dill, pressing it lightly into the cure mixture.
3. Wrap and Weight:
   1. Tightly wrap the entire salmon fillet and dish with several layers of plastic wrap, ensuring no liquid can leak out.
   2. For an extra layer of security, you can wrap it in aluminum foil as well.
   3. Place a second pan or a cutting board on top of the wrapped salmon. Add a light weight on top (e.g., a few cans of food, a heavy skillet, or a brick wrapped in foil). This gentle pressure helps to encourage the formation of the brine and firm up the fish.
4. Cure in the Fridge (with a Simple Timeline):
   1. Transfer the weighted salmon to the refrigerator. Cure for 36-48 hours. We recommend aiming for 40-42 hours for a perfectly balanced flavor and texture.
   2. Every 12-24 hours, flip the salmon fillet over (re-weighting it) to ensure even curing. You should see liquid brine pooling in the dish – this is normal and a sign the cure is working! The salmon will also become noticeably firmer to the touch.
5. Rinse, Dry, and Rest:
   1. Once cured, unwrap the salmon. You'll notice it's firmer and has changed color.
   2. Quickly rinse the salmon under cold running water to remove excess cure and dill. Alternatively, you can gently wipe it clean with a damp paper towel if you prefer a slightly saltier finish.
   3. Pat the salmon very dry again with paper towels.
   4. Place the gravlax on a clean plate, uncovered, and return it to the fridge to rest for 30-60 minutes. This resting period helps the texture firm up further, making it easier to slice cleanly.
6. Slice Like a Pro:
   1. Place the gravlax, skin-side down, on a clean cutting board.
   2. Using a long, thin, sharp slicing knife (a salmon knife or carving knife works best), start at the tail end of the fillet.
   3. Hold the knife at a shallow angle (on a bias) and make long, smooth strokes, slicing against the grain of the fish as thinly as possible, separating the flesh from the skin.
7. Mustard-Dill Sauce (Hovmästarsås) Ingredients
   1. 2 tablespoons Dijon mustard
   2. 1 tablespoon whole-grain mustard (optional, but highly recommended for texture and flavor)
   3. 1 tablespoon white wine vinegar or apple cider vinegar
   4. 1 teaspoon honey or granulated sugar
   5. 1/4 cup neutral oil (like canola, grapeseed, or sunflower oil)
   6. 2 tablespoons fresh dill, finely chopped
   7. Salt and freshly ground black pepper to taste
8. Mustard-Dill Sauce Step-by-Step Instructions
9. Whisk Mustard, Vinegar, and Sweetener:
   1. In a small bowl, combine the Dijon mustard, whole-grain mustard (if using), vinegar, and honey (or sugar).
   2. Whisk vigorously until thoroughly combined and smooth.
10. Slowly Whisk in Oil to Emulsify:
    1. While continuously whisking, slowly drizzle in the neutral oil in a thin, steady stream. This gradual addition is key to creating a smooth, emulsified sauce. The mixture will thicken and become glossy.
11. Stir in Dill and Season:
    1. Once the oil is fully incorporated and the sauce is emulsified, stir in the finely chopped fresh dill.
    2. Taste and season with salt and freshly ground black pepper as needed.
12. Correct Texture:
    1. The finished sauce should be spoonable, glossy, and not runny. If it’s too thick, add a tiny splash of water or vinegar. If too thin, you can try whisking in a little more mustard or letting it chill in the fridge to firm up slightly.
