Leninade

Use 2:1 rich simple syrup for its listed portion.

Select and pre-chill a highball glass.

Prepare a garnish of an orange zest twist and a lemon slice.

Shake the vodka, triple sec, freshly squeezed lemon juice, grenadine, rich sugar syrup, and orange bitters with ice.

Strain the mixture into the ice-filled highball glass while pouring in the soda water.

Express the orange zest twist over the cocktail to release its oils, then discard.

Garnish with a wheel of lemon slice.
