2 pounds ground beef 1/2 cup chopped onion 1 1/2 cups ketchup 1/4 cup white sugar 1/4 cup white vinegar 1/4 cup prepared yellow mustard 1/2 teaspoon celery seed 3/4 teaspoon Worcestershire sauce 1/2 teaspoon ground black pepper 3/4 teaspoon salt

. Place the ground beef and onion in a large skillet over medium-high heat. Cook, stirring to crumble, until beef is browned. Drain. Transfer the beef and onion to a slow cooker and stir in the ketchup, sugar, vinegar and mustard. Season with celery seed, Worcestershire sauce, pepper and salt. Cover and simmer on Low setting for a few hours before serving.

Note: My grandma would have also used 1 tsp of oregano and simmered her's on the stove. She would have also replaced the "ketchup" with tomato paste and that's what I recommend
