Bittered Sling Chartreuse milkshake

This creamy and smooth drink resembles a milkshake but it packs a punch, and we're not talking about just adding a shot of something something to a shake. Lauren Mote of Bittered Sling created this drink with gin, green Chartreuse, juices and creme de cocoa, as well as chocolate bitters, for a sweet and comforting concoction. 

1 ½ oz. Tanqueray No. 10 gin
1/2 oz. White Crème de Cacao
1/2 oz. green Chartreuse
1/2 oz. orange juice
1/2 oz. lime juice
3/4 oz. simple syrup
2 dashes Bittered Sling Malagasy Chocolate Bitters
1 egg, white only
raw cocoa bean, shaved, for garnish

Combine all ingredients, except cocoa, in a shaker with ice and shake vigorously. Strain over fresh ice in a collins glass.

Garnish with a few shavings of raw cacao bean.
