Amaretto is a sweet and nutty liqueur that is often enjoyed on its own or used in cocktails and desserts. To make homemade amaretto, you will need almonds, vodka, sugar, water, and almond extract. Start by toasting the almonds and crushing them into small pieces. Combine the crushed almonds with vodka in a jar and let it infuse for a few weeks. Then, make a simple syrup by boiling water and sugar together and let it cool. Combine the almond-infused vodka with the simple syrup and add almond extract for extra flavor. The result is a rich and flavorful amaretto that can be used to make cocktails like Amaretto Sour or enjoyed on its own over ice.
