Which ingredient follows the orange wedge in the Helluva Old Fashion recipe?

In the Helluva Old Fashion recipe, the traditional progression of ingredients typically involves muddling the orange wedge with sugar, followed by adding bitters, which enhances the flavor profile. The process then usually moves towards adding other components like syrup. While syrup can be an essential ingredient in some variations of an Old Fashioned, it generally follows the inclusion of bitters, as the classic recipe primarily focuses on bitters and sugar to create the base before sweetening further.

The use of syrup can help balance out the flavors, but it is not typically listed immediately after the orange wedge. Understanding the order of these ingredients can be significant as it reflects the cocktail's layering of flavors, which is crucial for a well-crafted Old Fashioned. In this context, bitters is a more foundational ingredient that is crucial for defining the cocktail's character, making it the appropriate choice to follow the orange wedge.
