Mix the first six ingredients together in a dish with several grinds of black pepper to make your marinade. Cut the ribs into thirds (about 4 cm pieces each) and drop them into the marinade. Toss, then refrigerate for 30 minutes to 1 hr.

Add a small splash of veg oil to a large pan on medium-high heat. Sear the meat for about 2 minutes on each side for a nice medium-rare. You don't want to overcook the ribs or else they'll become chewy. Fry in batches if you have to, to avoid overcrowding the pan. Remove the meat to a serving dish.

Once all the meat is cooked, drain any excess oil from the pan and add the marinade. Turn the heat down to medium and let simmer for about 5 minutes until the sauce is thick enough to coat the back of a spoon. Drizzle half the sauce over the meat and serve the remainder on the side for guests to help themselves. Garnish with a sprinkle of chopped green onion and/or sesame seeds.
