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

2 pounds ground beef

. 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
