There are, of course, MANY variations on the old fashioned. To make it a little less sweet, reduce the amount of Cointreau by 1/4 oz. Experimenting with different bitters (brands and flavors) is also a fun way to mix it up. If a Rye, or high-rye bourbon is your thing, it can add a bit of spice that I find appealing as we get closer to the holidays and cooler weather. Experiment! What is the worst thing that can happen, you have to make another drink???
