1 1/2 lb hamburger
1 onion chopped
2 1/2 T. vinegar
3 Tbl. brown sugar
1 C simply heinz ketchup
4 TBSP lemon juice
1/2 T. mustard
1/2 c water
Brown meat and onions add remaining ingredients and simmer, the longer the better. 
If too sour add more sugar or use less vinegar. I had to substitute vinegar for worcestershire sauce because it has corn something or other in it can’t remember what…lol
