01 - Preheat the oven to 400°F. Line a baking tray with parchment paper.
02 - In a small saucepan, combine soy sauce, mirin, honey, rice vinegar, ginger, garlic, and sesame oil. Bring to a simmer over medium heat.
03 - Stir in the cornstarch slurry and cook, stirring, until the sauce thickens (about 2 minutes). Remove from heat.
04 - Place salmon fillets on the prepared tray. Brush generously with the teriyaki glaze, reserving some for serving.
05 - Bake for 12–15 minutes, or until salmon is just cooked through and flakes easily with a fork.
06 - Switch oven to broil, and broil salmon for 1–2 minutes for a caramelized finish.
07 - Transfer salmon to plates, drizzle with extra teriyaki glaze, and sprinkle with toasted sesame seeds, spring onions, and coriander if using.
08 - Serve immediately with steamed rice or sautéed greens.
