OPTIONAL: for crispy salmon skin, sear skin-side down in a hot skillet with olive oil for 2-3 minutes, until browned and crispy, before proceeding.
Place salmon skin-side down on a rimmed baking sheet. Arrange top oven rack close to the broiler.
Mix all remaining ingredients (besides cilantro) in a small pot. Heat on stove top, whisking constantly, until sugar has melted and sauce is slightly thickened (about 3-4 minutes).
Brush some of the glaze on the top of the salmon.
Broil salmon for 8-10 minutes, removing to brush more glaze on top every two minutes, until it flakes easily with a fork and glaze has developed a thick layer on top.
Serve garnished with fresh cilantro.
Brown sugar creates a thick, sticky glaze, since it caramelizes well. Feel free to substitute it with a natural sweetener, such as honey or molasses, but be prepared for a thinner glaze on top.
