Boston sours are a delicious and impressive take on the classic whiskey sour! My version of the East coast cocktail is gorgeously hued, incredibly easy to make, and flavored with blood orange juice and ginger liqueur. This Blood Orange Boston Sour is one celebratory drink worth shaking up.

I love to serve this cocktail all winter long. It’s great for the holidays, New Year’s Eve and even Valentine’s Day!

About the Boston Sour

So about this show stopping whiskey cocktail. It looks pretty fancy but is one of the easiest cocktails you can make. Inspired by the classic whiskey sour, the addition of an egg white upgrades it to “Boston Whiskey Sour” status, or simply a Boston Sour.

Adding egg white to Boston Sours

You might be a bit skeptical about adding an egg white to your cocktail, and I understand that. But hear me out, it adds the most luxurious, frothy texture to the drink and has a way of bringing the flavors together. However, if you’re really freaked out about the egg white, opt for pasteurized egg white or leave it out — you’ll still have a delicious whiskey sour.

  1. I made the Blood Orange and Ginger Sour,I had to sub the ginger liqueur with ginger beer because I don’t have any and I am following stay at home orders during the Covid-19 pandemic. It was delicious and perfectly balanced. It was my first egg white cocktail and I am so glad I tried it. I will be trying it with the ginger liqueur as soon as I can get my hands on some. Thanks for a great recipe.
