1-First Step: Brew 1 ounce of espresso and pour it into a bowl to cool quickly; this should take about 2 minutes to avoid adding heat that could melt the ice later, using fresh beans for the best flavor results.

2-Second Step: Fill a cocktail shaker with ice, then add the cooled espresso to keep everything cold and ready for mixing; this step helps in creating that frosty texture when you shake it.

3-Third Step: Pour in 2 ounces of vodka, ½ ounce of coffee liqueur, and ½ ounce of simple syrup into the shaker; stir gently at first to combine the liquids before shaking for even distribution.

4-Fourth Step: Secure the lid on the shaker and shake the mixture very hard for 15-20 seconds until the outside feels frosty; this vigorous action traps air bubbles with the coffee oils to form the signature foam.

5-Fifth Step: Strain the mixture immediately into a chilled martini glass to preserve the foam on top; chilling the glass for at least 20 minutes beforehand keeps the drink cold longer.

6-Sixth Step: Optionally, add three coffee beans as garnish on top and serve right away; this final touch not only looks great but also adds a traditional symbol of good fortune.
