Cold Smock Salmon & Yellowtail Mosaic​

Step 1 (Dry Curing the Salmon): Debone the whole salmon fillet and completely remove the skin to guarantee a smooth, velvety texture in the final presentation. Thoroughly mix the coarse salt and brown sugar together to create the dry cure mixture. Place the salmon fillet into a tray or baking dish, then cover the entire surface uniformly with the salt-sugar mixture. Seal the dish tightly with plastic wrap and hold it in the refrigerator for 10 to 12 hours. This curing step draws out excess moisture, concentrates the natural sweetness of the flesh, and establishes the optimal structural density required for cold smoking.

Step 2 (Rinsing & Forming the Pellicle): Once the curing time is complete, remove the salmon from the dry brine and rinse it gently under cold running water to wash away any excess residual salt and sugar. Use clean paper towels to pat the entire surface of the fillet completely bone dry. Position the fish onto a wire rack to allow unrestricted air circulation all around it. Leave the salmon uncovered inside the refrigerator for 2 to 4 hours until a thin, slightly tacky layer known as a pellicle develops on the surface. This natural protein layer acts as a vital adhesive for the smoke particles to bind efficiently and yields an even coloration.

Step 3 (Cold Smoking Process): Set up your cold smoking unit with your choice of wood pellets, wood chips, or wood pucks according to your equipment specifications. Arrange the prepared salmon onto the wire rack inside the smoking chamber, ensuring there is sufficient clearance around each piece for the smoke to circulate freely. Cold smoke the salmon at a low temperature of 10°C to 18°C for 7 to 10 hours, adjusting the duration based on your target smoke intensity. It is critical to monitor and maintain this low temperature range throughout the process to prevent any thermal cooking of the protein while preserving its signature melt-in-the-mouth, juicy texture. When done, let the salmon rest on a cooling rack to allow the harsh smoke elements to dissipate and stabilize before moving it to cold storage.

Step 4 (Seasoning Customization & Plating): Depending on your menu concept, portion the cold smoked salmon and dress it with one of the five distinct seasoning profiles:

• Garlic Lemon: Lightly coat the salmon with 150ml of olive oil, fresh yellow lemon juice, finely chopped parsley, salt, and black pepper for a bright, clean finish.
• Honey Mustard: Combine the salmon with 150ml of olive oil, yellow lemon, honey, garlic, sriracha, salt, and black pepper to strike a balance between rich, sweet, and mild heat.
• Vietnam Green Chili: Introduce a Southeast Asian profile by mixing the salmon with 150ml of olive oil, yellow lemon, honey, garlic, sriracha, ginger, cilantro, orange, green chili, salt, and black pepper for a fragrant, punchy, citrus-forward flavor.
• Herby Italian: Toss the salmon with 150ml of olive oil, lemon juice, Italian seasoning, and dried chili flakes to build a classic herbal profile with a hint of spice.
• Sweet Spicy: Whisk 150ml of olive oil with rice vinegar, lemon juice, honey, and sriracha to create a vibrant sweet and tangy glaze.

Plating Presentation: Slice the finished cold smoked salmon into thin, delicate ribbons. Serve alongside traditional accompaniments such as sour cream, toasted bagels, shaved cucumber ribbons, artisan toast points, or a fresh crisp salad to accentuate the rich, smoky profile of the fish.

Step 1 (Fish Mosaic Preparation): Cut the Dutch Yellowtail loin into completely even, symmetrical logs to form a perfect mosaic blueprint when sliced later. Season lightly with salt and cover all sides uniformly with a layer of dried seaweed powder, rubbing gently into the flesh to incorporate a clean oceanic undertone. Spread multiple overlapping sheets of plastic wrap onto your work surface. Arrange the fish logs tightly flush against one another into your desired block formation, then roll tightly and firmly by hand to compress the fish into a rigid cylindrical log. Tie both ends securely to lock the structure. Cook in a sous-vide water bath at 46°C for exactly 26 minutes to yield an incredibly tender, translucent texture that maintains its natural elasticity. Once cooked, transfer the log immediately into an ice bath to arrest the cooking process and stabilize the mosaic structure. Chill in the refrigerator overnight before slicing.

Step 2 (Parsley Farce Layer): Place the fresh parsley leaves, 4g of salt, and 50g of white wine into a food processor and blend until completely smooth and a uniform deep green color is achieved. Add the 300g of cold fish trimmings and blend to form a cohesive, binding paste. Keep the temperature of the mixture strictly cold throughout this process to prevent fat separation. Once the paste turns smooth and glossy, add the 100g of double cream and pulse just until fully incorporated. Pass the mixture through a fine mesh sieve to achieve a perfectly silky texture. Spread the farce thinly onto a silicone baking mat and bake at 110°C for approximately 13 minutes until just set but still holding its vibrant green color. Allow to cool completely, then cut into neat portions using a round cutter. Lightly torch the surface immediately before plating to unlock its full aroma.

Step 3 (Black Pommes Soufflé): Brush 20g of squid ink onto a baking sheet or silicone mat, scatter the 80g of Codium seaweed on top, and dehydrate at 60°C until bone dry. Process the mixture into a fine powder to create an ultra-black, savory sea-infused seasoning. Peel the large waxy potato and slice using a mandoline to a precise thickness of 1mm to ensure even puffing. Arrange the potato slices in pairs; dust one side with potato starch and brush the opposing side with a very thin layer of egg white to act as a glue. Press the pairs firmly together and cut into shapes using a round cutter. Fry in clean oil heated to 170°C, continuously spooning the hot oil over the surfaces as soon as the potato slices float to force the pommes soufflé to expand and create a hollow core. Once beautifully golden and crisp, remove to drain on paper towels, then gently toss with the black seaweed powder.

Step 4 (Cucumber Broth): Chop the cucumber and celery into large chunks and transfer to a high-speed blender along with the shallot, green jalapeño, parsley, and white wine vinegar. Blend thoroughly to extract maximum fresh vegetable juice. Pass the mixture through a clean cheesecloth or paper filter to collect a crystalline, clean green broth. Whisk in 2g of xanthan gum to introduce a subtle viscosity, ensuring the broth clings elegantly to the plate. Only season with salt after the target viscosity is reached to protect the crisp freshness of the greens.

Step 5 (Yogurt Emulsion & Plate Assembly): Combine the 40g of egg white, sushi vinegar, 4g of salt, yogurt, and neutral oil in a blender and process until it emulsifies into a smooth, glossy sauce with a stable, thick pouring consistency. Transfer the emulsion into a piping bag. To serve, slice the chilled Yellowtail Mosaic log into perfectly even discs to showcase the internal geometric mosaic pattern. Position the baked parsley farce disk onto the plate as a foundation, place the mosaic fish slice on top or adjacent, and crown with the black pommes soufflé for a contrasting texture. Pipe dots of the yogurt emulsion around the dish and pour the chilled cucumber broth tableside right before serving to maintain an optimal equilibrium between richness, fresh brine, and cooling acidity.
