Gather your tools: You'll need a cocktail shaker (or a mason jar with a lid), a jigger for measuring, and a highball or Collins glass.
Measure the spirits: Pour ½ ounce each of vodka, white rum, gin, tequila, and triple sec into the shaker. This equal-parts base is what makes the best Long Island Iced Tea recipe so iconic.
Add the mixers: Squeeze in 1 ounce of fresh lemon juice and ½ ounce of simple syrup. The acidity from the lemon cuts through the booze, while the syrup adds subtle sweetness.
Fill with ice: Add a handful of ice cubes to the shaker – about halfway full. This chills everything quickly.
Shake it up: Secure the lid and shake vigorously for 10–15 seconds. You want it frosty and well-mixed, but not watered down.
Strain into glass: Fill your highball glass with fresh ice. Strain the shaken mixture over the ice, leaving room at the top.
Top with cola: Slowly pour 2–3 ounces of cola over the back of a spoon to create a layered effect. It mimics the look of iced tea!
Garnish and serve: Add a lemon wedge on the rim, maybe a mint sprig for aroma. Stir gently before sipping. Enjoy your homemade best Long Island Iced Tea recipe immediately for maximum refreshment.
