Creating the perfect Traditional Kalops involves patience and attention to detail. Follow these steps to ensure your stew is a success:

1. Prepare the Beef: Begin by cutting the beef chuck roast into 1.5-inch cubes. Pat them dry with a paper towel to ensure they brown properly.
2. Season and Brown the Beef: Season the beef cubes with salt and pepper. In a large Dutch oven or heavy-bottomed pot, melt the butter over medium-high heat. Add the beef in batches, ensuring not to overcrowd the pot, and brown on all sides. Remove the beef and set aside.
3. Cook the Onions: In the same pot, add the sliced onions. Cook until they are soft and translucent, about 5 minutes. Stir occasionally to prevent burning.
4. Add the Spices: Return the beef to the pot and sprinkle the flour over the mixture. Stir well to coat the meat and onions. Add the bay leaves, allspice berries, and peppercorns.
5. Deglaze and Simmer: Pour in the beef broth, scraping the bottom of the pot to release any flavorful bits. Add the sliced carrots. Bring the mixture to a boil, then reduce the heat to low. Cover and let simmer for 2 to 3 hours, or until the beef is tender.
6. Check and Adjust: Taste the stew and adjust the seasoning with salt and pepper as needed. If the stew is too thick, add a bit more broth to reach the desired consistency.
7. Final Touches: Remove the bay leaves and allspice berries before serving. Garnish with fresh parsley if desired.
