The Sugar Free Mark Twain Cocktail is our sugar free adaptation of the original that was referred to by Mark Twain himself! We found the original recipe we adapted printed in The Craft of the Cocktail: Everything You Need to Know to Be a Master Bartender, with 500 Recipes, by Dale DeGroff.
However, the reference from Mr. Twain dates back to a letter written to his wife from London in January of 1874 (and quoted from Mark and Livy: The Love Story of Mark Twain and the Woman Who Almost Tamed Him, by Resa Willis):
“Livy my darling, I want you to be sure & remember to have, in the bathroom, when I arrive, a bottle of Scotch whisky, a lemon, some crushed sugar, & a bottle of Angostura bitters. Ever since I have been in London I have taken in a wine glass what is called a cock-tail (made with those ingredients) before breakfast, before dinner, & just before going to bed.”
