Vodka martini
A vodka martini, also known as a vodkatini or kangaroo cocktail, is a cocktail made with vodka and vermouth, a variation of a martini. A vodka martini is made by combining vodka, dry vermouth and ice in a cocktail shaker or mixing glass. The ingredients are chilled, either by stirring or shaking, then strained and served "straight up" (without ice) in a chilled cocktail glass. The drink may be garnished with an olive, a "twist" (a strip of lemon peel squeezed or twisted), capers, or cocktail onions (with the onion garnish specifically yielding a vodka Gibson). The vodka  martini has become a common and popular cocktail. It is not a true martini, which is made with gin. List of variations. Variations on a vodka martini exist, usually by adding further ingredients to the cocktail. There is some debate as to whether or not these are true martini. An "Espresso Martini" is made with vodka, espresso coffee, coffee liqueur, and sugar syrup. It is popular in restaurants as a dessert. Many variations exist, but most involve shaking an espresso shot with the ingredients and served in a chilled martini glass. By shaking a fresh espresso shot it creates a  hard layer of cream which is garnished with three coffee beans in the centre. A "Porn Star Martini" traditionally uses vanilla flavoured vodka. This is mixed with Passoã and passion-fruit juice, before being served in a martini glass, accompanied by a shot glass filled with prosecco.
