Pisco Sour
Ingredients
- 2 tbsp granulated sugar (25g)
- 2 tbsp water
- 1 ounce limes – juiced, strained (about 1–2 limes) (~0.5 medium limes)
- 2 ounces pisco
- 1 large egg – white only
- 1 cup ice cubes – for shaking
- Angostura bitters – 2–3 dashes on foam (for garnish)

Instructions
- 1.
Make a quick simple syrup: Combine the sugar and water in a small saucepan over low heat, stirring just until the sugar fully dissolves, 1–2 minutes. Remove from heat and let cool briefly.
- 2.
Juice the limes and strain to obtain 1 ounce (2 tbsp) of clear juice; discard pulp and seeds.
- 3.
Add the pisco, the strained lime juice, 1.5 tbsp of the simple syrup from Step 1, and the white from 1 large egg to a cocktail shaker. Seal and dry-shake (no ice) vigorously until slightly foamy, 10–15 seconds.
- 4.
Add the ice cubes to the shaker. Seal and shake hard until the shaker is very cold and the mixture is thick and frothy, 12–15 seconds.
- 5.
Double-strain into a chilled coupe or small rocks glass.
- 6.
Dot the foam with 2–3 dashes of Angostura bitters. Serve immediately.
Pisco sour is a bright, velvety cocktail built on the floral, grape-driven spirit pisco, lifted by fresh lime and rounded by a silky egg-white foam. The texture is lush yet refreshing, with a fine balance of tartness and gentle sweetness that lets the pisco’s fruit and spice notes shine. A few dashes of aromatic bitters on the foam add a fragrant, slightly spicy top note and a handsome finish.
Born in South America, pisco sour is widely regarded as a Peruvian icon, though Chile also claims a closely related version. The drink traces to early 20th-century Lima, where it evolved from a whiskey sour at Morris’ Bar; later bartenders refined it with egg white and bitters to create the now-familiar profile. Over time, it became Peru’s national cocktail, celebrated annually and served in homes and bars alike, while regional interpretations continue to coexist across the Andes.
