Little Princess Cocktail - Light Rum & Sweet Vermouth Savoy Classic

The Little Princess Cocktail is as spare as classic cocktail formulas get: equal parts light rum and sweet vermouth, shaken cold and served up. The rum provides a clean sugarcane base while the vermouth adds sweetness, herbs, spice, and wine-like depth. With no citrus, syrup, or bitters, the character of both bottles stays clearly exposed.

From the Savoy Cocktail Book

The Little Princess appeared in Harry Craddock's 1930 The Savoy Cocktail Book, where the formula called for equal parts Bacardi rum and Italian vermouth. The drink was shaken and strained into a cocktail glass. A reliable earlier origin or named creator is not clearly documented, so the Savoy publication is the safest historical reference point.

What You'll Need

Ingredients

• Light Rum: provides a clean, lightly sweet sugarcane backbone.
• Sweet Vermouth: adds herbal complexity, spice, fruit, and rounded sweetness.

A clean white rum is the closest substitute for light rum. Another quality rosso or sweet vermouth can replace the specified vermouth, although different brands can noticeably shift the sweetness and botanical profile.

Equipment

You'll need a cocktail shaker, jigger, cocktail strainer, ice, and a chilled cocktail glass.

Equal Parts, Very Different Roles

The appeal of the Little Princess comes from contrast rather than complexity. Light rum is relatively restrained, allowing the vermouth's herbs, spices, and wine character to become unusually prominent. At the same time, the rum gives the drink enough alcoholic backbone to prevent it from drinking like fortified wine alone.

Because the recipe is exactly equal parts, bottle selection has a larger effect than the short ingredient list might suggest.

Substitutions & Variations

Use a lightly aged rum for additional vanilla, oak, and caramel character.

A richer sweet vermouth creates a fuller and more aromatic drink, while a lighter style keeps the rum more noticeable.

For a modern preparation, stir the drink with ice instead of shaking it. Stirring produces a clearer, silkier texture, but shaking is the historically published Savoy method.

An expressed lemon or orange peel can be added as a modern aromatic garnish, although the original published recipe does not require one.

Helpful Tips

Keep opened sweet vermouth refrigerated. Vermouth is wine-based and loses freshness after opening much faster than distilled spirits.

Use a rum you enjoy on its own. There are only two ingredients, so weak or harsh bottle choices are difficult to hide.

Measure equal portions accurately. Changing the ratio quickly shifts the drink from rum-forward to vermouth-dominant.

Shake with plenty of ice until thoroughly chilled, then strain promptly into the chilled glass.
