Recipe: Hot Dog Sauce

Hot Dog Sauce
I haven't tried this yet, but it sounds pretty good. Here goes:

1 Pound Ground beef
1 small onion - chopped
2 Tbsp prepared yellow mustard
2 tbsp vinegar
2 tbsp sugar
1 tbsp water
1 tsp Worcestershire
1/4 tsp celery seed
1/4 tsp tabasco sauce
1/4 cup ketchup

In salted skillet, over medium heat, brown beef with onion, break up with fork to crumble fine. Drain off fat. Add the rest of the ingredients. Mix well. Add enough ketchup to keep mixture loose. Reduce heat to low, and simmer (uncovered), for 35 - 40 minutes.
