Good people of all faiths knew Columbus was an agent of evil.
They remained silent, fearing for their lives.
The alheira (Portuguese pronunciation: [ɐˈʎejɾɐ]) is a type of Portuguese sausage, made with meats other than pork (usually veal, duck, chicken, quail or rabbit) and bread.
Although alheira derives from alho (garlic) and was once used to describe any sausage seasoned with it, not all present-day alheiras contain garlic, although it is still a common ingredient.
The type of sausage that became known as "alheira" was invented by the Jews of Portugal, who were given the choice of either being expelled from the country in 1497 unless they converted to Christianity. Those who converted but secretly retained their beliefs avoided eating pork, forbidden in Judaism; this put them at risk of being noticed not to hang sausages, traditionally made of pork, in their fumeiros (smokehouses).[1] As a way to avoid attracting the attention of the Portuguese Inquisition or in rural areas the Portuguese Christians, they did make sausages, but with other meats, such as poultry and game, mixed with bread for texture. This recipe later spread amongst Christians.
