Check 2-3 strips salmon skin for scales and use a small knife or fish scaler to remove them. Rinse them with water then pat them dry thoroughly with kitchen paper.
Start preheating a pan over medium-high. While you wait, sprinkle the salmon skin with 1 pinch salt and pepper and ½ tsp cornstarch. Rub all over both sides to evenly cover and dust off any excess.
Add 1 tbsp cooking oil to the pan and place the salmon skin with the scale side facing up. Avoid moving it while it fries. Once golden and crispy on the edges, flip and crisp up the other side.
Once crispy all over, turn off the heat and transfer to a wire rack or kitchen paper to drain the excess oil and cool.
Take a large mixing bowl and add ½ tbsp olive oil, ½ tbsp toasted sesame oil, ½ tbsp Japanese soy sauce (koikuchi shoyu), 1 tsp toasted white sesame seeds, 1 tsp wasabi paste, ½ tsp lemon juice, ½ tsp honey and ⅛ tsp ground black pepper. Whisk thoroughly until emulsified.
Cube 1 avocado, and cut 1 Japanese cucumber and 60 g smoked salmon into bitesize pieces. Place them in the bowl with the dressing and gently mix until evenly coated.
Arrange 50 g mixed leaves in a serving bowl and spoon the dressed mixture over the top. Use your hands to crush the salmon skin into small pieces and sprinkle it over the salad.
Serve immediately and enjoy!
Notes
Leave no water on the skin: Wet skin spends the heat of the oil on boiling off water first. It fries up damp in places and crisps unevenly.Judge the crunch after it cools: Cool the skin on the rack, then break one piece to test it. A clean crack means it is ready.If it will not snap once cool: Return the skin to the pan over medium-high and fry again until crisp all over. Cool it on the rack and test it once more.Whisk until it emulsifies: A split dressing tastes stronger in one bite and weaker in the next. Keep whisking until it comes together thick and creamy, and every bite carries the same flavor.Dress the plate just before eating: Keep the leaves and the dressing apart until the salad goes to the table. The leaves start to wilt the moment the dressing touches them.
