Dan's espresso martini recipe

This is my espresso martini recipe.

• 1 oz cold espresso
• 1 1/2 oz vodka
• 1 1/2 oz Kahlua
• 1 oz creme de cacao

I make the espresso fresh and let it cool for about 15 minutes.   After mixing, I pour it into a martini glass with crushed ice.   For ease, sometimes, I do one part of each ingredient and that works well too.
