Framboise liqueur, which originated in France, takes its name from the French word for the sweet and tart red berry from which it is distilled. If you are preparing one of the many cocktails that calls for framboise liqueur and have none around, fear not, for you might already have a suitable substitute already at your disposal.
Many fancy specialty cocktails list framboise liqueur as an essential ingredient, but you can substitute other raspberry-flavored liqueurs in its place. A few top-shelf American equivalents exist that have the same taste, consistency and quality. If you are concerned about the substitute's price, you can always substitute it with lower-priced liqueurs that mix raspberries with brandy. Often, a drink's required measurement of framboise liqueur is so small that other fruit-flavored liqueurs, like orange liqueur or crème de cassis, will do in a pinch.
Infused and Flavored Spirits
When mixing cocktails that require framboise liqueur with liquors like vodka and rum, you can substitute multiple ingredients with a raspberry-infused or -flavored liquor. A martini that calls for vodka and framboise liqueur can combine the needed ingredients with a raspberry-infused vodka, or a cocktail made with rum and framboise liqueur could be made with raspberry-flavored rum. As a plus, vodka is such a neutral spirit for which raspberry vodka may be substituted in drinks that call for tiny amounts of the liqueur.
Not all of framboise liqueur's substitutes have to pack an adult punch. Drinks that need framboise liqueur have enough potency that a non-alcoholic substitute will do. Raspberry extract, potent in its own right, can successfully double for framboise liqueur; you will need to mix in only a sixth of the original measurement. Raspberry syrup, the kind found in coffee shops, and raspberry juice also works to simulate framboise liqueur's specific taste, but add about a fourth of what's required in the recipe so as to avoid overpowering the other ingredients.
From the Source
For more desperate situations requiring a framboise liqueur substitute, you can always create a your own sweetened raspberry paste. Muddle 2 parts fresh raspberries with 1 part sugar until you get a gelatinous consistency. Add a dollop of your creation to your drinks to get the necessary raspberry taste. Adding equal parts of a non-flavored vodka or brandy to the paste gives it the added kick, but the resulting "liqueur" won't be as refined as the original.
