pumpkin, squash or gourd
Confusingly, either zucca or zucchetta can mean any number of varities of squash, pumpkin and decorative gourd. They're a standby all over Italy, in soups, pies and tarts, and especially as a filling for pasta, such as Mantua's tortelli di zucca. The flowers, like those of courgettes, are popular stuffed with ricotta and deep-fried: fiori di zucche.
