To make this cocktail it's really quite simple. In a cocktail shaker add 45ml of Canadian Club, 15ml sweet vermouth, a dash of bitters and lastly, top up with ice. Stir the ingredients well, diluting the mixture a little. I have seen bartenders shake manhattans, which is fine, I personally prefer to stir the drink, as you have more control over the dilution. It's a good idea to taste the drink through a straw every so often while you stir. You don't want to dilute the spirits to much. Once your happy with the taste, strain mixture into a chilled martini class and drop a maraschino cherry in the glass. I like to serve this drink in a martini glass, but it's sometimes often served on the rocks in a short glass.
One great thing about this drink is if you don't like rye style whiskey, you can still make a great Manhattan variation. You could have a "Cuban Manhattan" made with dark rum, a "Brandy Manhattan", made with obviously brandy, a "Tijuana Manhattan", made with anejo tequila and the list goes on. Hope you have some fun and enjoy your Manhattan!
