Heat oil in a medium nonstick skillet over medium. Season salmon with salt and place in skillet skin side down. Cook, shaking pan occasionally to redistribute oil in skillet, until skin is very crisp and deep golden brown, 7–9 minutes. Turn salmon and continue to cook just until very lightly browned on the flesh side (by this point it should be nearly cooked through), about 2 minutes longer. Using a spatula to hold fish from tumbling out of skillet (or just transfer salmon to a plate while you do this), pour off fat from skillet. (Return fish to skillet if needed before proceeding.) Reduce heat to low and add glaze; cook, stirring occasionally, until it begins to thicken, about 1 minute. Baste salmon with glaze and cook, basting occasionally, until glaze evenly coats fish, about 1 minute longer.
