The Bartender's Guide, or how to mix all kinds of plain and fancy drinks

In 1862, Thomas finished Bar-Tender's Guide (alternately titled How to Mix Drinks or The Bon-Vivant's Companion), the first drink book ever published in the United States. The book collected and codified what was then an oral tradition of recipes from the early days of cocktails, including some of his own creations; the guide laid down the principles for formulating mixed drinks of all categories. He would update it several times in his lifetime to include new drinks that he discovered or created. The first edition of the guide included the first written recipes of such cocktails as the Brandy Daisy, Fizz, Flip, Sour and variations of the earliest form of mixed drink, Punch.
