1 oz of blue curacao liqueur
4-6 oz of Cranberry Juice
1 oz of silver tequila (or Tequila)
In a highball glass with ice pour tequila then blue curaco... it shoudl look kinda like windex at this point. Add the juice and you're good to go. If all amounts are done properly the drink should be a dark purple with a small blue ring at the bottom. Suggest garnishing with lemon.
