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.
Chill a rocks glass and prepare the garnish before mixing.
Add the measured still ingredients and a lime peel to the shaker; the peel seasons the regal shake and is not a measured juice addition.
Add ice and shake until cold, strain back into the empty tin to remove the ice, then seal and shake again without ice to build the foam.
Fine strain into the prepared rocks glass over fresh ice.
Squeeze a fresh lime peel over the surface for its oils, then remove it.
A thoughtful finish
- The regal shake uses a lime peel in the shaker to add a small citrus-oil accent.
- Use the pasteurized egg product specified for this build, and measure it before adding it to the tin.
- Chill the serving glass as well as the mixture so the first sip stays cold.
Common mistakes
- Adding bottled lime cordial instead of juice introduces extra sugar beyond the agave syrup.
- Insufficient shaking leaves the egg poorly incorporated and the texture uneven.
- A warm serving glass quickly undoes the chilling achieved during mixing.
A few good questions.
What is in a Mezcal Sour?
Mezcal Sour is made with mezcal, lime, agave syrup and egg white in a foamy agave sour.
Can I scale a Mezcal Sour for more servings?
Multiply every measured ingredient by the same serving count. Prepare the measured still ingredients ahead if useful, but chill, shake or stir each serving as directed; add any carbonated finish at service.
Can I leave out the egg?
Leaving out the egg changes the texture; the selected recipe includes it. An egg-free version should be labeled as an adaptation rather than presented as the same build.
Who created the Mezcal Sour?
The cited source credits Simon Difford (selected published version) in March 2025. The recipe-version note identifies any later adaptation.
Variations
- Egg-free presentation — Editorial adaptation: omit egg white and label the result as an egg-free variation; it will lack the selected build’s foam and texture, and still requires ingredient-label checks.
- Alternate citrus peel — Editorial presentation variation: try a different fresh citrus peel for the surface aroma while keeping the liquid formula unchanged; identify it as a garnish change.
