Metropolitan

The Metropolitan sounds and looks like a classic cocktail, one as old as the Manhattan or Martinez, but the matter is rather unclear.

1 1/2 oz brandy
1 oz sweet vermouth
1/2 tsp sugar syrup
2 dashes Angostura bitters

Pour the brandy, sweet vermouth, sugar syrup and Angostura bitters into a cocktail shaker with ice cubes.
Shake well.
