How to make the cocktail Rattlesnake

Rattlesnake is a wild cocktail from the 1930 Savoy Cocktail Book that comes with the famous warning: it will "either cure rattlesnake bite, or kill rattlesnakes, or make you see them!"

This frothy whiskey sour gets its bite from Rye Whiskey and lemon juice, plus a mysterious hint of absinthe that adds an herbal kick. The egg white creates a silky foam on top that's perfect for creating snake-like patterns with bitters – making this drink as fun to look at as it is to sip, with just enough danger to keep things interesting.
