I found this recipe on TGI Friday's website a few years ago. I made it several times, and must admit its pretty close to the sauce served at the restaurant.
1 tablespoon onion powder
1 tablespoon garlic powder
1 tablespoon tabasco sauce
1 cup pineapple juice
1/2 cup Jack Daniel's Whiskey
2 cups brown sugar
2 beef bouillon cubes
4 tablespoons worcestershire sauce
Recipe
Combine all ingredients in a small saucepan. Bring to a boil, reduce heat, and simmer for 15 minutes. Allow to cool. Use as a glaze on any any grilled meat or for dipping.
