While I’m always hesitant for such sweeping statements about an entire culture and ethnicity, if you’re interested in a sort of How To Be an Italian Guide for Dummies, this would be a good start.
Espresso is a way of life, food is important (it truly is all about prosciutto) and those expressions are very useful, but I wouldn’t say Nutella can be a substitute (each food has it’s own use) and not all pasta is made from scratch. There’s egg pasta, and then regular pasta. The egg pasta is the one that can be made from scratch, but I wouldn’t say it’s all that common when you can buy damn good egg pasta for very, very cheap at the store.
I do, however, have more than one friend with those exact same yellow glasses. ha!
