Five-Star BBQ Sauce

1 onion, diced fine
1/2 lb. celery, diced fine
1/2 lb. margarine
1 1/2 c. brown sugar
3 Tbsp. granulated garlic
2 Tbsp. dry mustard
2 Tbsp. chili powder
2 1/2 c. apple cider vinegar
1 Tbsp. non-iodized salt
1 1/2 c. tomato paste
3/4 c. Worcestershire sauce
5 1/2 c. Heinz ketchup

Saute onion and celery until onion are clear. In a shaker jar, put 1/2 c. cold water, mustard and chili powder and shake well. Put all other ingredients in a 1 1/2 gallon pot and bring to a boil, stirring often. Add shaker contents and reduce heat to simmer. Simmer 15 minutes, stirring often. Refrigerate until needed.

Note: The onions and celery can be put through a blender or food processor for a finer sauce. Do not liquefy veggies. If the sauce is to be used on the side; cook 5 to 10 minutes longer.
Add a pint of water if you want a thinner sauce.
