  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
     1/2  cup           wine vinegar
   2      tablespoons   dry mustard
   1 1/2  cups          salad oil
   1      tablespoon    coarse pepper
     3/4  cup           soy sauce - maybe a little less
   2 1/4  teaspoons     salt -- (optional)
     1/3  cup           lemon juice
   1 1/2  teaspoons     parsley
     1/4  cup           Worcestershire
   2      cloves        garlic
     1/2  cup           barbecue sauce
                        --ketchup based - I use Kraft original
                        brown sugar to taste

Preparation:

Put all in blender - keeps months in refrigerator. This recipe has a lot of the same ingredients as the Big Boy BBQ Sauce but does not have an overpowering ketchup flavor. I believe the Kraft sauce is used to give a "smoke" flavor to the sauce.
