Combine the stock, whiskey, brown sugar, cinnamon and salt in a small pot. Bring it to a low boil over medium heat while you stir it a couple of times. Then add the carrots and let the mixture gently boil together for about 20 minutes. The liquid will reduce to a syrup coating the carrots. Depending on the size of the carrots, there may be excess syrup. Reserve it as a topping for later on ice cream or pancakes sealed in the refrigerator! Serve the carrots immediately when they are done on the side of whatever main course dish you want. They go with anything!
