Prepare Your Tools: Get your cocktail shaker, jigger, strainer, and martini glass ready. Chill your martini glass by placing it in the freezer for about 15 minutes or filling it with ice water.

Combine Ingredients: In the cocktail shaker, add the vodka, pineapple juice, triple sec, and fresh lime juice.

Add Ice: Fill the shaker with ice to the top.

Shake Well: Secure the lid on the shaker and shake vigorously for about 15 seconds until the mixture is well-chilled.

Strain and Pour: Empty the ice water from your chilled martini glass, or retrieve it from the freezer. Using a strainer, pour the mixture into the glass.

Garnish: Add a pineapple slice or lime wheel to the rim of the glass for that final touch.
