Today, it's trendy to seek out local ingredients that are fresh and in season, but a couple of centuries ago, local was the only option. The greatest American cities were known for certain drinks — created from specific base spirits and mixers — because that's what was available there. As the city's culture evolved, the cocktails evolved too — and the elixir came to stand for the geographically unique experience. Jonny Raglin — "JR" below — of Comstock Saloon in San Francisco shares his favorite cocktails from the great American cities — each one having long represented its birthplace. While other drinks may be associated with these cities, the elixers below were actually conceived of or popularized and perfected in the heart of the city. Jonny dug up the original recipes and adapted them to the modern palate, using the very best ingredients and precise proportions. Pick a couple favorites and master the art of crafting them, with Jonny's help, in your liquid kitchen.
