The first publication of a bartenders' guide which included cocktail recipes was in 1862 - How to Mix Drinks; or, The Bon Vivant's Companion, by Professor Jerry Thomas. In addition to recipes for punches, sours, slings, cobblers, shrubs, toddies, flips, and a variety of other mixed drinks were 10 recipes for cocktails. A key ingredient differentiating cocktails from other drinks in this compendium was the use of bitters. Mixed drinks popular today that conform to this original meaning of cocktail include the Old Fashioned whiskey cocktail, the Sazerac cocktail, and the Manhattan cocktail.
