Manhattan cocktail

Method

1. Mix the bourbon whiskey in a jug with the vermouth and Angostura bitters. Chill until needed (up to 24 hours).
2.  For each strip of orange, run the outer side round the rim of a low-ball or small wine glass, then put the strip inside the glass with a maraschino cherry.
3. To serve, add as much ice as you can to the jug, stir to combine for 30-40 seconds, then strain into the 6 prepared glasses.
