Elderflower liqueur is a floral and fragrant spirit that can be enjoyed on its own or used in cocktails and desserts. To make homemade elderflower liqueur, you will need elderflowers, vodka, sugar, and water. Start by infusing the elderflowers in vodka for a few weeks. Then, make a simple syrup by boiling water and sugar together and let it cool. Combine the elderflower-infused vodka with the simple syrup and let it rest for a few more weeks. The result is a delicate and aromatic liqueur with a hint of sweetness. Use elderflower liqueur to make cocktails like Elderflower Collins or enjoy it over ice with a splash of soda water.
