In a large pot or Dutch oven, heat a drizzle of olive oil over medium-high heat. Season the short ribs generously with salt and freshly cracked black pepper.  Once the oil is shimmering, add the ribs. Sear them on all sides until they develop a beautiful brown crust, about 3-4 minutes per side. Remove them from the pot and set aside.

In the same pot, add a bit more olive oil if needed, then toss in the sliced onions. Sauté for about 5 minutes until they are translucent.  Add the garlic and cook for an additional 1-2 minutes until fragrant. This step is crucial. The foundation of your stew lies here.

Next, stir in the chopped carrots and celery. Cook for about 5 minutes until they start to soften. This will add another layer to the stew's profile.

Pour in the red wine and use a wooden spoon to scrape up any delicious browned bits stuck to the bottom of the pot. This process is essential for depth of flavor.

Now, sprinkle in the flour. Stir well to combine; this will help thicken the stew as it cooks. Gradually add the beef stock while stirring.  Bring the mixture to a simmer, then return the seared short ribs to the pot.

Add the fresh thyme, bay leaf, half a teaspoon of balsamic vinegar, and smoked paprika to the pot. Stir to distribute all flavors evenly.

Cover the pot and reduce the heat to low; let the stew cook for about 2 to 2.5 hours. This is where the magic happens.  The beef becomes incredibly tender, and the flavors meld beautifully. Stir occasionally to ensure nothing sticks.

After a couple of hours, add the quartered Yukon Gold potatoes. Cook for another 30-40 minutes until they are fork-tender. Then stir in the sweet green peas during the last 5 minutes of cooking.

Before serving, taste and adjust the seasoning with salt and pepper. Remove the bay leaf and thyme sprigs.
