Prepare the Sauce: In a slow cooker, mix together water, ketchup, tomato paste, brown sugar, vinegar, mustard, and salt. Stir well until the brown sugar and salt are completely dissolved.

Add the Ribs: Place the beef back ribs into the slow cooker and stir them to coat evenly with the sauce.

Cook: Set the slow cooker to the Low setting, cover it with the lid, and let the ribs cook for 8 hours, or until they are tender and flavorful.

Serve: Once cooked to perfection, serve the ribs hot, straight from the slow cooker, with your favorite side dishes. Enjoy!
