Brew a strong Earl Grey: steep one tea bag or 1 tablespoon loose-leaf in 4 ounces of just-off-boil water for 4 minutes. Strain and cool to room temperature. If the tea is too concentrate for balance, dilute with a splash of cold water.

Combine base ingredients

In a cocktail shaker, pour 2 oz Ron Zacapa 23, 2 oz cooled Earl Grey, 0.5 oz vanilla syrup, and 1.5 oz heavy cream. If using egg white for silkiness, add 0.5 egg white now.

Dry shake

If you used egg white, perform a dry shake (shake without ice) vigorously for 10–15 seconds to emulsify and build foam.

Wet shake

Add a generous handful of ice (or a large cube) to the shaker and shake vigorously for 12–15 seconds until the shaker is cold to the touch and the mixture is well chilled and slightly diluted.

Double strain

Double-strain the cocktail into a chilled coupe or Nick & Nora glass (or over a large ice cube in a rocks glass if you prefer). Double straining (through a fine mesh) removes ice shards and tea bits, yielding a silky texture.

Finishing & Aromatic

Garnish and aromatics

Express a strip of orange peel over the surface to release oils and rub it around the rim if desired, then drop it into the drink. Optionally grate a little vanilla or orange zest over the foam and float a star anise or a thin bergamot twist for an extra aromatic note.

Serve

Serve immediately while chilled. Sip slowly to appreciate the contemplative interplay of rum, bergamot from the Earl Grey, and smooth vanilla cream.
