Heat the olive oil in a 6 quart dutch oven over medium high heat. Season 3-4 short ribs with the salt and pepper.
Sear all sides in the hot oil until a deep brown crust forms.
Remove and repeat with remaining short ribs. Turn the heat to medium and set ribs aside. Remove most of the excess oil and salt in the pot. There should on be a few tablespoons to coat the pot. See photo above.
Add the onion and sauté for 2-3 minutes.
Add the carrots and celery. Sauté for 2-3 minutes.
Add the garlic, oregano, thyme, and rosemary. Sauté for 1-2 minutes.
Add the tomato paste and sauté for 1-2 minutes.
Add the flour and cook for 2-3 minutes.
Deglaze the pan with the red wine, scraping any bits off the bottom of the pot.
Add the broth, worcestershire sauce, and fish sauce. Bring to a boil.
Add all of the ribs back into the liquid so they are submerged. Add the bay leaves and parmesan rind.
Cover and simmer on low for 2 1/2 - 3 hours or until the ribs are tender. If the ribs are not tender, continue simmering until they reach desired tenderness. See instructions for other cooking methods below. Remove ribs and simmer sauce longer to thicken if needed. The sauce will thicken as it cools.
