Prep the Veggies: Start by chopping the onions, celery, and carrots. Set them aside for later.
Season the Lamb: Rub the lamb racks with some olive oil and season generously with salt, pepper, and some lemon thyme. Let them sit for a few minutes while you prepare the next steps.
Brown the Lamb: Find a large pot that comfortably holds both lamb racks. Over medium-high heat, add the lamb and brown it on all sides for about 3 minutes per side. Once browned, remove the lamb and set it aside.
Sauté the Aromatics: Pour the rest of the olive oil into the same pot. Add the sliced onions and cook for 2 minutes, until they begin to soften. Sprinkle in a little turmeric powder and stir it in.
Add the Veggies and Garlic: Now, add the chopped celery, carrots, and minced garlic to the pot. Cook them for another 2 minutes, or until softened.
Deglaze and Season: Pour in the red wine, dark chocolate balsamic vinegar, and chicken broth one by one. Stir everything well to scrape up any browned bits from the bottom of the pot. Add more salt and pepper to taste, along with the remaining lemon thyme.
Simmer and Flip: Return the seasoned lamb racks to the pot and bring the mixture to a boil. Reduce the heat to low, cover the pot, and simmer for about an hour. After 30 minutes, remove the lid, gently flip the lamb, and continue simmering uncovered for another 30 minutes.
Serve Up Sizzling Success: Once the lamb is cooked through and beautifully tender, turn off the heat. Leave some broth in the pot to keep the vegetables nice and juicy. Immediately slice and serve your tender, succulent lamb on a bed of flavorful dill rice or your chosen side dish.
