Start by placing your martini glass in the refrigerator, to develop a chilled, frosted appearance that will add to the taste and visual appeal of your orange martini.
Next, load up your cocktail shaker – fill the shaker about halfway with ice cubes or crushed ice. Then, proceed to pour 60 ml of vodka, 15 ml of dry vermouth, 15 ml of orange liqueur, 1 dash of orange bitters and 30 ml of fresh orange juice into the cocktail shaker.
Cover the cocktail shaker (make sure you secure the lid), and shake it for approximately one minute until all the ingredients are mixed together, and the exterior of the shaker begins to feel cold.
Once everything is blended, strain the orange martini into your chilled martini glass. Garnish your drink with an orange twist, and serve chilled.
