Heat vegetable oil and garlic in frying pan. Add one or multiple spare ribs at a time and let it brown.
In a pressure cooker pot, add water, soy sauce, sake, mirin, honey, ginger, scallion, and ribs. Cover pot and cook over high heat until the pressure is built, then lower to medium heat and cook for 10 minutes.
Turn off heat and let the pot release pressure before removing lid. Turn on heat again and let it simmer until there is no more liquid. Your pork ribs are completed!
