Cut the beef into 1-inch cubes.

In a large pot, heat a little oil over medium heat, then add the chopped onion, garlic, and ginger. Sauté until fragrant and the onion becomes translucent, about 5 minutes.

Add the beef to the pot and brown it on all sides.

Sprinkle the brown sugar over the meat and stir well to combine.

Pour in the water, vinegar, and pepper sauce, stirring to combine.

Add the black pepper, allspice, cloves, nutmeg, cinnamon, and bay leaves.

Bring to a gentle boil, then reduce the heat to low. Cover and let it simmer for about 3 hours, stirring occasionally.

Before serving, taste the sauce and adjust seasoning as needed.
