Fill a mixing glass with ice.
Add 30ml gin, 30ml Lillet Blanc, and 30ml sweet vermouth.
Stir with a bar spoon for 40–45 revolutions until well chilled and properly diluted.
Strain into a chilled coupe or martini glass, or over a large ice cube in a rocks glass.
Express an orange peel over the surface to release its oils, then place on the rim or discard as preferred.
Lillet Blanc is significantly less bitter than Campari, so this drink leans closer to a Martini in character than a traditional Negroni - if you want to nudge it back toward bitterness without abandoning the concept, a small barspoon of Suze or Salers works beautifully.
