Make the sauce: Combine the tomatoes, water, ou’, and salt in a pot. Place over medium to high heat. Bring the mixture up to a boil and lower the heat to medium low to maintain a steady simmer. Continue to cook for about 20 to 30 minutes until the flavors combine and the sauce thickens.

Meanwhile make the meatballs: Combine ground beef, rice, salt, all spice and egg in a large bowl. Use your hands to mix ingredients together to ensure that they are all well distributed. Shape about ½ tablespoon of the meat mixture into a ball and tuck it into the tomato sauce in the pot. Continue shaping and placing the meatballs into the sauce. 

Place a lid ajar and cook the meatballs in the sauce, maintaining a simmer. Cook for about 1 hour and 30 minutes, stirring occasionally. Taste sauce in the middle of cooking, and correct for salt and sweet and sour levels. Add more salt if needed, a bit of sugar if you want it sweeter, or more ou’ if you want it tangier.

Serve hot over white rice.
