Preheat oven to 300
Season the short ribs with the salt. Cook the short ribs in a hot pan with some oil on all sides to brown. Transfer to a baking dish.
Add the remaining short rib braise ingredients to the baking dish. Cover and bake for 1 hour. Flip the short ribs and bake another hour. Then uncover them and continue to bake until the short ribs are tender and just about falling apart.
Add the oil to the risotto pan over medium heat. Add in the carrot, celery, and onion and season with salt. Cook 8 minutes to soften.
Add in the garlic, half the butter, and the rice and cook another 5 minutes, stirring often, to lightly toast the rice.
Add about half cup of wine and stir. Scrape the bottom of the pan to deglaze.
Continue stirring and adding a little wine when it becomes dry. Cook about 20 minutes until you use all the wine.
Remove the short ribs from the cooking liquid when they are done, and start using that braising liquid in the risotto the same way you were using the wine, adding a little at a time as needed.
If you run out of that liquid before the rice is tender, you can finish with either water or beef stock.
When the rice is just tender, add enough more liquid so it is loose and soupy, not tight. Remove from heat and stir in the other half of the butter and parm. Taste and add seasonings if needed.
Serve on a plate with two short ribs on top and more parm if needed.
