Heat oil in a large casserole pan on a high heat. Season the short ribs with salt and pepper, place in the pan, and then brown on all sides (takes about 6-8 mins). Take the short ribs out of the pan and place on a plate.
Turn the heat down to low, place the diced onion into the pan, season with a pinch of salt and pepper, and gently cook for 5 minutes, stirring regularly until softened.
Whilst the onions are cooking, make the glaze by mixing the paprika, cinnamon, cayenne, dark brown sugar, honey, and water in a small bowl. Spread half of it over the short ribs.
Add the garlic to the onions and give a stir. Allow to cook for 30 seconds, then add the tinned tomatoes, stock, Worcestershire sauce, and brown sauce. Bring to the boil and then place the short ribs on top. Place a lid on the pan and place in the oven for 3 hours (check it occasionally. If it starts to look too dry, add in a splash of water).
After three hours, take out of the oven and give everything a little stir.
Spread the rest of the glaze on the short ribs, and sprinkle with the light brown sugar. Turn up the oven to 200C/400F (fan), and cook uncovered for 20-30 minutes until the short ribs are dark and sticky looking.
Take out of the oven, sprinkle with chilli flakes and fresh coriander, and serve with boiled rice.
