How to Make an Old Fashioned With Pecan- and Cinnamon-Infused Whiskey

We dropped by the Cosmopolitan of Las Vegas to get some insider tips on making an Old Fashioned—with a twist.

Here, Mariena Mercer, chef mixologist at the Chandelier Bar demonstrates how to make one of their most popular libations: Original Sin.

“An Old Fashioned is typically whiskey, ice, bitters, and a little bit of sugar,” Mercer says. “I’ve taken the bitters and sugar elements and put them in an ice sphere. As the whiskey makes its way down and percolates, it’s going to melt that ice and change the flavor of your cocktail.”

Here’s how to make it on your own.
