Step 1: Prepare the Ribs

1. Preheat your oven to 300°F (150°C) if baking, or set your slow cooker to low.
2. Remove the membrane from the back of the ribs for better texture and flavor absorption.
3. Pat the ribs dry with paper towels, then season them generously with salt, black pepper, and garlic powder on both sides.

Step 2: Cook the Ribs

Oven Method

1. Wrap each rack of ribs tightly in aluminum foil and place them on a baking sheet.
2. Bake for 2.5 to 3 hours, or until the ribs are tender but still hold their shape.

Slow Cooker Method

1. Place the seasoned ribs in the slow cooker, cutting them into smaller sections if necessary to fit.
2. Cook on low for 6-8 hours, or until tender.

Step 3: Make the Sweet Chili Glaze

1. In a small saucepan, combine the sweet chili sauce, soy sauce, honey, lime juice, fish sauce, garlic, ginger, and red pepper flakes.
2. Simmer over medium heat for 5-7 minutes, stirring occasionally, until the glaze thickens slightly.

Step 4: Glaze and Caramelize

1. Once the ribs are cooked, remove them from the oven or slow cooker and discard any accumulated juices.
2. Preheat your broiler or grill.
3. Brush the ribs generously with the sweet chili glaze on both sides.
4. Place the ribs under the broiler or on the grill for 5-7 minutes, turning and basting with more glaze until the sauce caramelizes and becomes sticky.

Step 5: Serve

1. Transfer the ribs to a serving platter and garnish with chopped cilantro, sliced green onions, sesame seeds, and lime wedges.
2. Serve hot with your choice of sides, such as rice, noodles, or a fresh salad.
