Gary Regan’s most recent Chronicle column is out as well, with the Professor’s substitute bartender Jake filling in. Jake gets an email from the Professor with the recipe for today’s cocktail, a close relative of the Cocktail of the Day above. This sounded fantastic, and it was — we made them last night . We sure do love St. Germain (and its pretty bottle), and it’s always a pleasure to use pisco in something other than the ubiquitous Pisco Sour.

The classic proportions are in effect.

The Peruvian Elder-Sour

2 ounces pisco.
1 ounce St. Germain Elderflower Liqueur.
1/2 ounce fresh lime juice.

Shake with ice and strain into chilled cocktail glass. Garnish with lime wheel.

I’m gonna start playing with St. Germain and silver tequila next, probably just swapping out the pisco, but I’m sure someone’s already thought of that.
