Another Mackey original. This one was inspired by the pisco sour. The egg yolk gives it a silky texture and beautiful pink foam on top. I used Urban Moonshine citrus bitters, but Angostura bitters would work fine.
2 oz freshly squeezed lemon juice
2 oz rye whiskey
1/2 oz grenadine
white of small egg
Mix all ingredients in a cold shaker. Shake VERY well and VERY vigorously and strain into a chilled glass. Float about three dainty drops on the foam. The bitters shouldn’t mix into the drink- they’re meant to be a little foamy kick.
