Ginjinha is a traditional Portuguese liqueur made from ginja berries, a type of sour cherry. It is typically produced by infusing the berries in aguardente, a strong Portuguese spirit, along with sugar and sometimes additional flavorings like cinnamon. Ginjinha is often served in small shot glasses, sometimes with a piece of the fruit included. This liqueur is especially popular in Lisbon and the nearby town of Óbidos, where it is commonly enjoyed as a refreshing drink. Visitors often savor it in local bars, where it is served neat or with a splash of sour cherry juice.
