Fireball Cinnamon Whisky Liqueur, 70 cl

The Whisky Sour is versatile – whether you decide to switch up the Whisky, sour or sweet element, the end result will almost always be delicious – just remember to stick to that golden ratio of 2 parts Whisky, 1 part sour and 1 part sweet (but hey, if your personal preference is different, you do you!). If you’re after something sweeter, bourbon or brandy are both great options. Prefer a smokier sour? A scotch will be your go-to.When it comes to the sour substitution, lime is a more subtle option if you find lemon too overpowering, alternatively you can opt for a sweeter pick like orange or a more savoury choice like grapefruit. And when it comes to the egg white and no egg white debate, well, it’s completely up to you!
