Boston Cooler over a lump of ice and a spiral of lemon peel in a heavy tumbler, beside the peeled lemon.

The story behind the recipe

A Boston Cooler is two sodas in one glass: sarsaparilla and ginger ale in equal parts, poured over a lump of ice and the whole peel of a lemon in a large tumbler. Robert Vermeire printed it in 1922 in Cocktails: How to Mix Them, a London bar book, and finished the recipe with an order: “Serve and drink when fizzy.”

Coolers with and without

Vermeire’s coolers page opens by saying that “some are made with liquors; others are absolutely non-alcoholic drinks,” and this is one of the second kind. The long lemon peel is the same trick as the Horse’s Neck, and sarsaparilla is the root-beer side of the soda fountain, close to a Fountain Root Beer. It isn’t the Detroit Boston Cooler, a ginger-ale float with ice cream. The bar book’s other drinks for the dry guest are told in What Did Bartenders Mix for Non-Drinkers in the 1920s?

Making it today

Sarsaparilla is still bottled, and root beer is the nearest swap. Both sodas should be cold, and pour them gently down the side of the glass so the fizz lasts.

Recipe notes

When adjusting quantities

Keep sarsaparilla and ginger ale in equal parts, and build each glass separately.

Notes

Quantities mentioned in these notes don’t change when you adjust the batch.

Vermeire gives no glass size; a large tumbler of about 12 fl oz takes 4 fl oz of each soda and leaves room for the ice and peel. Keep the peeled lemon for its juice; it doesn’t go in the drink.
