Easter or Resurrection Sunday commemorates Jesus' resurrection from the dead, a Christian celebration and holiday mentioned in the New Testament as having happened the third day after his death by the Romans at Calvary. It is a 40-day cycle of fasting, prayer, and penance at the end of the Passion of Jesus.

On Easter Sunday, tradition requires that everyone – relatives or friends – sit together and celebrate with lamb dinner. It's clear that the whole of Easter is about sweets and eating fish on Good Friday evenings.

You've never asked, though, why are these foods so important to the festivities? A big reason for our creation of a conventional Easter menu is the celebration of Lent and the need to give up certain foods.

Why do we eat lamb on Easter?

The lamb is the most common emblem of Easter worldwide. In Christianity, the reference to lamb comes from the book of Genesis, when Abraham was invited to sacrifice his son.

In recent centuries, the meeting with a lamb, particularly at Easter, was considered a lucky omen. It was a common superstition that because of its religious symbolism, the demon who could assume the shape of all such creatures could never come in the form of a lamb.

The Benedictine monks wrote in the 7th century a prayer in favor of lambs' blessing. A couple of hundred years later, the Pope took it, and a roasted lamb became and the characteristic of the Pope's Easter Dinner ever since.
