Ginja is a traditional Portuguese cherry liqueur, primarily produced in the region of Óbidos. It is made by infusing ginja berries, a type of sour cherry, in alcohol, often with the addition of sugar and other ingredients like cinnamon or cloves. The drink is typically served in small cups, sometimes with a piece of the fruit inside. This liqueur is popular as a digestif and is enjoyed both straight and in cocktails. Ginja has become a symbol of local culture in Óbidos, where it is commonly offered to visitors, making it a must-try for those exploring Portuguese cuisine.
