Select the day's Neighborhood Rotator configuration (server/bartender indicates base spirit and chosen modifiers). In a cocktail shaker, add 2 oz base spirit, 0.75 oz aromatic modifier, 0.5 oz liqueur or bitter component, 0.5 oz fresh citrus juice and 0.25 oz simple syrup.

Add bitters

Add 2 dashes of the chosen cocktail bitters to the shaker so the aromatic profile layers with the modifiers.

Shake with ice

Fill the shaker with ice (enough to chill and dilute properly). Secure the lid and shake vigorously for 10–15 seconds, until the shaker is cold to the touch and slightly frosted.

Strain & Finish

Choose serve style

Decide whether to serve up (straight into a chilled coupe) or on the rocks (over fresh ice in a rocks glass). If serving on the rocks and using the sparkling top, add 1.5 oz club soda or tonic to the glass after pouring the shaken mix.

Double strain

Strain the contents of the shaker through a Hawthorne strainer (and fine mesh if desired) into the prepared glass to remove ice shards and pulp.

Garnish

Express a citrus twist over the drink to release the oils, then rim the glass with the twist and drop it in (or add a wheel). If using a fresh herb, lightly clap it between your hands to release aroma and either garnish on top or slap it against the glass rim.

Final check

Taste (or offer a small adjustment) — if the drink feels too tart, suggest +0.25 oz simple syrup; too sweet, suggest +0.25 oz citrus next batch. Present to guest with the day's chosen spirit and modifiers named.
