Korean Pork Ribs: Super Tender Sweet Soy Sauce Braised Ribs

Cut the pork back ribs into individual pieces.
In a mixing bowl, dissolve 1 tbsp sugar in cold water, add the ribs, and soak for 30 minutes to remove the blood.
Cut the onion in half and slice the green onion into large 5 cm pieces.
Mix all the sauce ingredients together.
Add the soaked ribs, soy sauce mixture, onion, green onion, and garlic to a pressure cooker.
Pour in the water, close the lid, and bring to a boil over high heat. Once steam starts coming out, reduce to low heat and simmer for 40 minutes.
* If using a pressure cooker, 15 minutes is enough, but the longer it cooks, the more tender the ribs become.
If the liquid reduces too much and seems like it might burn, add water in 50 ml increments.
Open the lid, remove the onion and green onion, and reduce the sauce over medium-high heat.
* If there is too much liquid, you can remove some before reducing.
Finely slice the green onion and chop the nuts.
Plate the ribs and top with green onion, nuts, and sesame seeds.
