Pisco Sour
Pisco, lime, sugar and egg white under a dash of bitters. Peru's national drink, and the best argument anywhere for the dry shake.
Built to the standard modern spec; not yet tested in our kitchen. How we test.
The recipe.
Scaling adjusts quantities only. Prepare shaken drinks in individual portions.
Let’s make a good drink.
Add the pisco, lime juice, simple syrup and egg white to a shaker with no ice.
Dry shake hard for 15 seconds to build the foam.
Add ice and shake again for 12-15 seconds.
Strain into a chilled coupe, let the foam settle for a few seconds, then drop the bitters onto the surface.
A thoughtful finish
- Dry shake first, then shake with ice. Doing it in one go with ice chills the egg white before it can emulsify and you get a thin, patchy foam.
- Let the foam settle for five or ten seconds before you add the bitters, or the drops sink instead of sitting on top.
- Peruvian pisco is unaged and bottled at proof with nothing added — it is a much more aromatic spirit than its clear colour suggests, and a cheap one will show.
Common mistakes
- Skipping the dry shake, which is the whole technique.
- Using pasteurised egg white from a carton, which will not whip to the same volume. Fresh is noticeably better.
- Stirring the bitters in. They are an aromatic garnish — you smell them as you drink.
A few good questions.
Lime or lemon?
The IBA spec says lemon. Peruvian practice uses limón, a small key-lime-like citrus closer to lime than to a Eureka lemon. Lime is the better approximation for most people; lemon makes a rounder, less sharp drink.
Is raw egg white safe?
Raw egg carries a small salmonella risk. Use fresh, properly refrigerated eggs, and avoid it if you are pregnant, elderly, very young or immunocompromised. Aquafaba — chickpea liquid — works as a vegan substitute and foams well. This is general information, not medical advice.
What is the difference between Peruvian and Chilean pisco?
Different countries, different rules. Peruvian pisco must be distilled to proof from specified grape varieties with no water added afterwards and no ageing in wood. Chilean pisco permits dilution and some oak. They taste meaningfully different.
Why is my foam collapsing?
Not enough dry shake, old eggs, or a greasy shaker. Make sure the tins are properly clean — fat kills egg foam.
Variations
- Chilean Pisco Sour — No egg white, no bitters.
- Whiskey Sour — Bourbon in place of pisco, with the same egg-white technique.
- Amaretto Sour — Amaretto and bourbon with egg white.
- Maracuyá Sour — Passion fruit added to the pisco sour build.
Where it comes from
c. 1920s · Lima, Peru · Victor Vaughen Morris · Morris' Bar
Victor Vaughen Morris, an American who had come to Peru to work on the railways, opened Morris’ Bar in Lima in 1916 and was serving a pisco sour there by the early 1920s; the bar’s own receipts and newspaper advertising document it. Mario Bruiget, a Peruvian bartender who trained under Morris, is credited with the refinements that make the modern drink — the egg white and the dash of Angostura on top. Both Peru and Chile claim pisco and the sour nationally, and the two countries make the drink differently: the Peruvian build with egg white and bitters is the one described here, while the Chilean version typically omits both.
