With a history dating back to the 15th century, this sausage delicacy was invented by the Jewish community in Portugal. When given the choice between converting to Christianity or being expelled from the country, the Portuguese Jews opted for the latter, but decided to keep practicing Judaism in secret.

In order not to draw unwanted suspicion while still abiding by Kosher law, they began making and eating sausages using meat other than pork, such as rabbit or poultry. Nowadays, Barroso-Montalegre sausage is made by combining different meats and bread with spices that provide it with a unique flavor.

Pimento, sweet red paprika (known locally as pimentão), onions, parsley, and olive oil give alheira de Barroso-Montalegre its unmistakable aroma and color.
