food is an important part of the tradition, even more about pizza

Not for all Italians. My paternal grandmother is from northern Italy, but moved to the UK with her new husband shortly after the second world war. My father, growing up with an Italian housewife as mother, experienced a lot of Italian cuisine, but never saw pizza until he went away to university in the mid-60s.

Upon returning home one vacation, he said to his mother "I discovered a wonderful Italian dish at university called pizza... why did you never cook this?" -- only to be met by the scornful reply "Pizza? That's what poor people eat!"
