Step 1: Prepare the Pineapple

1. Peel the pineapple and remove the core. Slice it into rings, wedges, or chunks, depending on your preference. Pat the slices dry with a paper towel to remove excess moisture.

Step 2: Make the Glaze

1. In a small bowl, whisk together soy sauce, honey (or brown sugar), rice vinegar, garlic, ginger, chili flakes, and sesame oil. Taste and adjust the sweetness or heat to your liking.

Step 3: Caramelize the Pineapple

1. Heat a large skillet or grill pan over medium-high heat. Add the butter and let it melt.
2. Place the pineapple slices in the skillet in a single layer. Cook for 2-3 minutes on each side until caramelized and golden brown. Remove from the skillet and set aside.

Step 4: Cook the Glaze

1. Reduce the heat to medium and pour the glaze into the skillet. Let it simmer for 2-3 minutes, stirring frequently, until it thickens slightly.

Step 5: Combine Pineapple and Glaze

1. Return the caramelized pineapple to the skillet. Toss gently to coat each piece in the glaze. Cook for an additional 1-2 minutes to allow the flavors to meld.

Step 6: Serve

1. Transfer the pineapple to a serving plate. Drizzle any remaining glaze from the skillet over the top. Garnish with toasted sesame seeds, cilantro, or sliced red chilies if desired.
