Preheat oven to 300 degrees F, and grease a large baking sheet. Sprinkle both sides of the ribs with salt and pepper, then lay them in a single layer on the baking sheet. Bake for 2.5-3 hours until the ribs are juicy and tender.
4 lbs pork spare ribs, Salt and pepper
While the ribs are baking, prepare the sauce. Place the pear, tamari sauce, rice vinegar, fish sauce, garlic, ginger, and green onions in a food processor until thick and smooth. Set aside.
1/2 Asian pear, 1/4 cup tamari sauce, 1 tbsp rice vinegar, 1 tsp fish sauce, 2 garlic cloves, 1 inch fresh ginger, 2 green onions
Once the ribs are done, pour out the oil that's been cooked off. Cut the ribs into sections using kitchen shears or a knife.
Slather on half of the sauce on top of the ribs, then broil for 3 minutes. Remove from oven, flip the ribs, and repeat with the rest of the sauce. Broil for 2-3 minutes until the sauce is thick and caramelized.
Sprinkle with chopped green onions and sesame seeds before serving.
