Raspberry liqueur is a sweet and fruity spirit that can be enjoyed on its own or used in various cocktails and desserts. To make homemade raspberry liqueur, you will need fresh raspberries, vodka, sugar, and water. Start by mashing the raspberries and combining them with vodka in a jar. Let the mixture infuse for a few weeks, then strain out the solids. Make a simple syrup by boiling water and sugar together, and combine it with the raspberry-infused vodka. Let the liqueur rest for a few more weeks to develop its flavors. The result is a vibrant and flavorful liqueur that can be used to make cocktails like Raspberry Martini or Raspberry Collins.
