Mix all the ingredients together in a bowl and rub the pork ribs with the mixture to coat them thoroughly.
Place the ribs in the pressure cooker with the water and cook on a high flame. After one whistle, reduce the flame and cook for 25 minutes.
Allow the cooker to cool down and release the pressure. Remove the ribs, taking care to ensure the meat doesn't fall off the bones. Heat the oven on grill / broiler mode to 220℃ and line a baking tray with baking parchment.
To make the glaze, place a saucepan on a low flame. Ad the sesame oil, ggrated ginger and garlic and saute for a few seconds, taking care not to burn them. Add the stock from the cooker along with all the other ingredients and bring to a gentle simmer. Cook the sauce for a few minutes till the sauce has thickened slightly to a glossy, coating consistency.
Liberally brush the sauce on the ribs and grill on the topmost rack of the oven for 2 minutes on each side till they are lightly browned and shiny.
