NOTE: This sauce is great for perking up any simply grilled meats, poultry or fish. Brush it on just minutes before you pull the meat off the grill.
1/2 cup Jack Daniel's Tennessee Whiskey
1/2 cup soy sauce
1/2 cup ketchup
1 cup brown sugar
1 teaspoon garlic powder
Combine all ingredients in a small saucepan. Simmer until slightly thickened, about 5 minutes.
Makes about 1 1/2 cups.
