The cauldron has long been the symbol of witches' brew on Halloween. But this year omit the eye of newt and wing of bat and instead serve up this inky-black cocktail. Activated charcoal is even sold in supplement stores and is supposed to help clean out the body's toxins, so your friends could even thank you.
*Adds a jet-black hue and a light, smoky flavor to the cocktail
Combine all ingredients except garnish in a shaker with ice and shake vigorously. Strain into a coupe glass. Garnish with a lemon slice.
