Squash didn't actually play a large part in Italian cuisine until the 20th century. It was considered common food and not fit for the "noble" classes. Boy, were those nobles missing something. Some say barucca is a play on the Italian word verruca, which means wart, while others say it is from the Hebrew word baruch, meaning holy. Personally, we like that Italians would name zucca barruca the holy squash. Zucca barucca is not yet available in the States, but butternut squash works just as beautifully in this succulent sauce for fusilli.
