This was totally worth buying the tequila for. A lot more tasteful than a traditional Long Island Ice Tea. With this drink I made my own sweet and sour mix using lime juice instead of lemon as lime complements cranberry better.
12.5ml Light Rum
25ml Sweet and Sour Mix (lime)
120ml Cranberry Juice
Lime Wheel (for garnish)
Shake liquids with ice, pour into a sling glass with ice then garnish with lime wheel.
