5 ml of gomme syrup (or simple syrup)
5 ml of grenadine syrup
5 ml of Kahlua coffee liqueur (or coffee liqueur)
10 ml of blue curacao liqueur
First, put the Kahlua at the bottom of the shot-glass, then pour in the gomme syrup. The gomme sinks to the bottom, then add a splash of grenadine in the middle. It will sink through the kahlua and create a lava-lamp style effect. Then add the Blue Curacau on top of the Kahlua.\r
