Between the Sheets

Equal parts of three spirits plus a little less lemon is the IBA shape. Measure all four; eyeballing the rum against the cognac is how this drink goes muddy. Shake harder than you would a Martini — citrus and orange liqueur need the aeration. Double-strain so the pale gold stays clear. A thick twist dumps pith; use a thin peel and express it away from the sugar-sensitive drinker if you have one.

The rum should be a clean white — Plantation 3 Stars or a decent agricole blanc — not a funky Jamaican that will shout over the cognac. VSOP cognac (Rémy Martin or Hine) keeps dried fruit in the middle. Cointreau beats generic triple sec here because the drink is already a three-spirit pile-up; cheap orange liqueur makes it taste like a bar special. If it reads sweet, your lemon was tired. If it reads thin, you shorted the Cointreau.

Harry MacElhone is the usual credit, at Harry’s New York Bar in Paris in the 1920s — a Sidecar split with rum and a name that sold itself in the Jazz Age. The IBA keeps it on The Unforgettables list. It is not a novelty drink; it is the Sidecar template taught to share the base between brandy and rum. Skip the wink in the name and make it like any other citrus classic: cold, measured, and bright.

Sidecar

Drop the rum and move to 2 oz cognac, ¾ oz Cointreau, ¾ oz lemon when you want the brandy to lead without the extra spirit. Same glass, same shake, calmer drink.

Maiden’s Prayer

If the rum feels like too much traffic, use gin instead of cognac and rum: gin, Cointreau, lemon, and a little orange juice. Lighter, more floral — use it when the bottle on the bar is gin.
