Prepare the Espresso:

Brew a strong espresso and allow it to cool. You'll want it cold to prevent melting the ice too quickly.

Combine Ingredients:

In a shaker, combine the cooled espresso, Baileys Irish Cream, and vodka if you're including it.

Add a handful of ice cubes.

Shake:

Secure the lid on the shaker and shake vigorously for about 15 seconds. This not only chills the drink but also introduces air, giving the martini a nice froth.

Strain and Serve:

Strain the mixture into a chilled martini glass. The aim is to have a nice foam on top.

Garnish:

For a classic finishing touch, float three coffee beans on the foam. This garnish is not just decorative; in Italian culture, it symbolizes health, wealth, and happiness.

Enjoy:

Serve immediately and enjoy the luxurious blend of coffee and creamy Baileys.
