I like to take the salmon out of the fridge about 20 minutes before cooking so it isn't ice cold when it hits the pan. Pat each fillet completely dry with a paper towel, since moisture is the enemy of a good sear. Season both sides generously with salt and pepper.
While the salmon comes to room temperature, I whisk the honey, soy sauce, vinegar, and minced garlic together in a small bowl. It looks thin and unremarkable at this stage, but don't worry. Once it hits the hot pan with the salmon, it transforms completely.
I heat a drizzle of olive oil in a non-stick skillet over medium-high heat until it shimmers. The salmon goes in first, cooking undisturbed for 3 to 4 minutes until the underside turns deep golden. Then I flip it carefully and let the other side cook for another 2 to 3 minutes.
Once both sides are golden, I pour the honey garlic sauce directly into the pan around the salmon. It bubbles up almost immediately and starts to thicken within a minute. I spoon it over the top of the fillets a few times so every bit gets coated.
I always check the side of the fillet to judge how cooked it is inside. I like mine coral and slightly translucent in the center, which is medium-rare, but you can cook it a bit longer if you prefer it more well-done. Remember, salmon keeps cooking a little even off the heat.
Once the sauce has thickened to a glossy glaze, I transfer the salmon to plates and spoon any extra sauce from the pan over the top. A sprinkle of sesame seeds and sliced chives finishes it off beautifully, and it's ready to eat right away.
