The Secret Is OUT!!! I have been making this for many years... My Father Charles Sullivan, named it Mambo Sauce because it tastes so good it made him want to dance! The SECRET part of the name was because everyone wanted the recipe and I only gave it to special people.... and loved to tease my brother Jim with it.. because he was the Bar-B-Q King in the family.... until I made this sauce! He added a couple drops of hot sauce and liquid smoke... and calls it his "Secret Sauce"....(we all know the true story!) LOL We have had a lot of fun and good food and fellowship with this recipe.... I now pass it along to all of my special friends at Just A Pinch! Enjoy!
