What is a Pisco Sour?

The traditional pisco sour has pisco, lime, simple syrup, and egg white. According to Wikipedia, “A pisco sour is an alcoholic cocktail of Peruvian origin that is typical of the cuisines from Peru and Chile. The drink’s name comes from pisco, which is its base liquor, and the cocktail term sour, in reference to sour citrus juice and sweetener components.

What is Pisco?

Pisco is a brandy from Peru and Chile made from grapes. It reminds me a little of tequila because of the sharp, earthy aroma. It definitely tastes smoother than it smells. The citrus and egg white help balance out the pungent nature of the pisco. The Pisco Sour is the most common drink I know of for this spirit and how I discovered it. I first tried a Pisco Sour at a Peruvian restaurant in San Francisco and it has been a favorite of mine since then.

How to Make a Grapefruit Pisco Sour

  1. Place all of the ingredients into a cocktail shaker and dry shake for 15-20 seconds.
  2. Add a scoop of ice to the shaker and shake again for another 15-20 seconds until everything is nice and cold. Strain through a fine-mesh strainer into your favorite cocktail glass.
  3. Garnish with a slice of citrus if desire and enjoy!

Alternative to Using Egg White in a Cocktail

You will not have a traditional Pisco Sour if you do not add an egg white. However, you can still enjoy this cocktail without the egg white. See my notes in the recipe card on the USDA comments on egg whites in the recipe. Not everyone is comfortable adding egg white to their drink, and that’s ok.

An alternative to adding egg white to cocktails is to substitute aquafaba instead. Aquafaba is the “bean liquid” usually from garbanzo beans/chickpeas. It’s gluten-free and dairy-free and an excellent alternative for people with an egg allergy, who don’t consume eggs, or do not want to use raw egg white. Simply substitute 1-2 tbsp of aquafaba for 1 egg white.

If you omit egg white or the alternative altogether, I would suggest shaking the ingredients in a cocktail shaker and pouring over fresh ice in a glass.

Notes

  • *The US Department of Agriculture (USDA) considers it safe to use raw eggs if they are pasteurized. Bottom Line: Raw eggs may contain a type of pathogenic bacteria called Salmonella, which can cause food poisoning. However, the risk of an egg being contaminated is quite low. Please proceed at your own risk and decide if you are ok with this. I have never had an issue.
