Place one of your favourite martini glasses in refrigerator until chill properly.
Meanwhile, take a cocktail shaker and half fill it with cracked ice.
Pour 2 ounces of blended Scotch whisky, 1 ounce of ruby port, 1/2 ounce French vermouth and 2 dashes of orange bitters into the cocktail shaker.
Now, close the lid of your cocktail shaker thoroughly and shake it for few seconds until all ingredients mix well.
Take out the martini glass from refrigerator and strain the Chancellor Cocktail into it. Garnish your drink with orange zest twist if you want and serve immediately.
