BBQ Beef

8 lbs roast beef or pork
32 oz ketchup
6 tsp Dry mustard
1/2 Tbs. Liquid smoke
1-2 cup brown sugar (depending on how sweet you like it)
2/3 cup vinegar

Cook roast until it shreds, add above ingredients, simmer and serve

This feeds a lot but you can cut down the recipe if you have a smaller roast
