What is added to the Sazerac besides Bourbon and Simple Syrup?

In the preparation of a Sazerac cocktail, bitters play a crucial role in enhancing the overall flavor profile of the drink. Traditionally, the Sazerac uses Peychaud's bitters, which are essential to creating the cocktail's distinctive taste. The bitters are added to the mix of Bourbon and simple syrup to balance the sweetness and provide depth and complexity to the cocktail.

The other options do not belong in a classic Sazerac. Cream, egg, and grenadine do not complement the intended flavor experience of this traditional drink, which focuses on the robust character of the whiskey highlighted by the herbal and aromatic notes from the bitters. Understanding the specific role of bitters in the Sazerac helps reinforce the importance of flavor balance in cocktail creation.
