Pat salmon dry and skin your salmon and dice into bite-sized pieces.
Heat butter in a skillet over medium-high. Sear salmon cubes on 2–3 sides until golden. Remove and set aside.
In the same pan, add honey, soy sauce, fresh ginger, garlic, and rice vinegar. Bring to a simmer.
Stir in the cornstarch slurry (cornstarch mixed with water) and cook until thick and glossy.
Return salmon to the pan and toss until coated and lacquered.
Finish with sliced scallions, sesame seeds, and an optional drizzle of chili oil.
