The proportions for this drink have changed since it was invented in the 1920s, so feel free to adjust them to your liking.

• 2 oz Cognac (or brandy, if you’re on a budget)

• 1 oz Cointreau

• 1 oz lemon juice

• Garnish: Optional sugar rim; lemon or orange twist

If you like, run a cut lemon half around the rim of a chilled cocktail coupe and dip it in sugar. It’s more modern, though, to skip this step.

Combine Cognac, Cointreau and lemon juice in a cocktail shaker filled with ice; shake well and strain into the prepared cocktail glass. Garnish with lemon or orange twist. Serves 1.
