0.4 CupsOrange Juice
1 TbspPassion Fruit Syrup
0.2 CupsTequila
0.1 CupsGrenadine

Fill a tall glass with ice cubes half way and add the tequila. Top up with orange juice, add passion fruit syrup and give the cocktail a stir. Once mixed slowly pour in the grenadine, which should sink to the bottom, coloring the rest of the drink on its way down.
