Fill your cocktail shaker halfway with ice cubes to chill the drink thoroughly.
Add the vodka, apple liqueur, green apple juice, fresh lime juice, and simple syrup to the shaker.
Secure the lid tightly and shake vigorously for about 15 seconds until the mixture feels cold and frosty with a slight chattering sound.
Remove the shaker lid and strain the mixture into a chilled martini glass, catching the liquid to create a smooth, vibrant green appearance.
Garnish the drink with a few fresh mint leaves placed gently on top or on the rim for a touch of freshness and visual contrast.
Your Halloween Poison Apple Martini is now ready to serve! Its shimmering green glow and spooky vibe make it a perfect centerpiece for your Halloween celebration.
