Using simple syrup instead of sugar in an Old Fashioned is a perfectly acceptable alternative. In fact, many bartenders and cocktail enthusiasts prefer using simple syrup because it dissolves more easily and evenly into the drink.
Simple syrup is made by combining equal parts sugar and water and heating until the sugar is fully dissolved. This creates a syrupy consistency that is easier to work with than granulated sugar. When making an Old Fashioned, you can use the same amount of simple syrup as you would use sugar, typically around half an ounce to one ounce.
However, if you're looking to elevate your Old Fashioned to the next level, rich syrup might be the way to go. Rich syrup, also known as 2:1 syrup, is made with a higher ratio of sugar to water, resulting in a thicker and sweeter syrup. This allows you to add the necessary sweetness to your cocktail without diluting it as much as regular simple syrup would.
The advantage of using rich syrup in an Old Fashioned is that it provides a more concentrated burst of sweetness without adding excess water to the drink. This can be particularly desirable if you prefer a stronger and less diluted cocktail. Additionally, the thicker consistency of rich syrup can contribute to a smoother mouthfeel and enhance the overall texture of the drink.
Now, you might be wondering how to make rich syrup. It's quite simple! To create a 2:1 syrup, you'll mix two parts sugar to one part water. For example, you can combine two cups of sugar with one cup of water. Heat the mixture over medium heat, stirring constantly until all the sugar is fully dissolved. Once the syrup has cooled, you can store it in a bottle or jar in the refrigerator for future use.
In terms of taste, using rich syrup instead of regular simple syrup can subtly alter the flavor profile of your Old Fashioned. The increased sweetness can accentuate the flavors of the whiskey or spirit you're using, and the thicker consistency can add a velvety texture to the drink. Some people also find that rich syrup provides a more balanced and smoother sweetness compared to using granulated sugar or regular simple syrup.
Ultimately, whether you choose to use regular simple syrup or rich syrup in your Old Fashioned comes down to personal preference. Both options will sweeten the cocktail effectively, but rich syrup offers the added benefit of minimizing dilution and enhancing the overall mouthfeel of the drink. So go ahead, experiment with both and see which one you prefer in your Old Fashioned!
