01 - Preheat oven to 400°F. Line a baking tray with parchment paper.
02 - Season salmon fillets generously with salt and freshly ground black pepper. Arrange them skin-side down on the prepared baking tray.
03 - In a small saucepan, combine pineapple juice, honey, soy sauce, grated ginger, vinegar, and minced garlic. Bring to a gentle simmer over medium heat, stirring occasionally.
04 - Once the mixture reaches a simmer, whisk in the cornstarch slurry. Continue cooking and stirring constantly until the glaze thickens to a glossy consistency, about 2 to 3 minutes. Remove from heat.
05 - Brush half of the prepared honey pineapple glaze generously over each salmon fillet, coating evenly. Reserve the remaining glaze for finishing.
06 - Bake in the preheated oven for 10 to 12 minutes, or until the salmon is just cooked through and flakes easily with a fork.
07 - Remove the salmon from the oven and brush with the remaining glaze. Garnish with chopped cilantro and finely diced fresh pineapple. Serve immediately alongside lime wedges.
