Preheat oven to 300.
Sear the short ribs on all sides in a very hot pan with some oil. Season with salt and pepper.
Add in the stock and spices and stir well to combine. Place into the oven and cook for 2.5 to 3 hours until tender.
Meanwhile, cook the onion and pepper in a little oil for about 5 minutes until softened.
Add the stock and bring to a simmer.
Whisk in the polenta and simmer on low for about a half hour, stirring occasionally.
Once tender, stir in the chocolate, parm, and butter until melted and combined.
To serve, plate the polenta, then top with the short ribs, drizzle on some of the short rib cooking liquid.
