1. Prepare the salmon
Pat the salmon cubes completely dry with a paper towel. Season lightly with sea salt and freshly ground black pepper, then toss with the cornflour until each piece is lightly coated.
2. Make the honey garlic sauce
In a small bowl, whisk together the honey, soy sauce, minced garlic, rice vinegar and chilli flakes until well combined. Set aside.
3. Cook the salmon
Heat the olive oil in a frying pan over medium-high heat until shimmering. Add the salmon cubes in a single layer, ensuring they are not overcrowded. Cook without moving them for about 2–3 minutes, or until a deep golden crust forms on the underside.
Turn the salmon pieces and cook for another 2–3 minutes until crisp on the outside and just cooked through.
4. Glaze and serve
Reduce the heat to medium and pour the honey garlic sauce into the pan. Gently toss the salmon in the sauce and allow it to bubble for 1–2 minutes until it thickens slightly and coats the salmon in a glossy glaze.
Remove from the heat and transfer the salmon bites to a serving plate.
Finish with sliced spring onions and toasted sesame seeds.
Serve immediately.
