Step 1: Make the honey pineapple glaze

1. In a small saucepan over medium heat, combine the pineapple juice, honey, soy sauce, garlic, and red pepper flakes (if using).
2. Bring the mixture to a simmer and cook for 4-5 minutes, stirring occasionally, until slightly thickened. Remove from heat and set aside.

Step 2: Prepare the salmon

1. Pat the salmon fillets dry with paper towels and season both sides with salt and black pepper.

Step 3: Cook the salmon
Option 1: Pan-seared

1. Heat olive oil or butter in a large skillet over medium heat.
2. Place the salmon fillets skin-side down and cook for 4-5 minutes, until the skin is crispy.
3. Flip the salmon and pour half of the glaze over the fillets. Cook for another 3-4 minutes, basting with the glaze, until the salmon is cooked through and flaky.

Option 2: Baked

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
2. Place the salmon fillets on the prepared baking sheet and brush generously with the glaze.
3. Bake for 12-15 minutes, basting with additional glaze halfway through, until the salmon is cooked through and flakes easily with a fork.

Step 4: Serve

1. Drizzle the remaining glaze over the salmon. Garnish with diced pineapple and chopped parsley or cilantro.
2. Serve with rice, quinoa, or roasted vegetables for a complete meal.
