1/2 oz of Vodka
1 drop of milk
1/2 oz of Midori melon liqueur (or watermelon liqueur)
1/2 oz of Malibu coconut rum (or Coconut Rum)
Shake Midori, Malibu and vodka with ice. Strain into a shot glass. Place a straw in milk and cover other end with thumb (to capture milk in straw). Place straw with milk about halfway into shot glass and use thumb to release 1 drop of milk in center of shot. This requires some practice, but if done properly, will form a white 'pearl' floating in the shot. Very tasty!
