|1 1⁄2 fl oz||Bourbon whiskey|
|1 fl oz||Freshly squeezed lemon juice|
|2⁄3 fl oz||Sugar-free sweetener|
|2 dash||Angostura or other aromatic bitters (optional)|
|1⁄2 fl oz||Pasteurised egg white|
This Whiskey Sour isn't very sour and those wanting a drier drink should consider reducing the sweetener to nearer 15ml (1/2oz).
Adding a couple of dashes aromatic bitters greatly contributes to the cocktail's flavour but this also adds trace amounts of sugar.
