A zuppa can be savoury or sweet (of the latter, the best known is zuppa inglese).
Some famous versions:
zuppa acida di trippa: pickled tripe soup. An acquired taste (Trentino-Alto Adige).
zuppa acida della Stiria: soup with pig's foot, tail, and ears, a hangover cure at New Year's (Friuli).
zuppa bastarda or zuppa lombarda: see fettunta.
zuppa di canederli di fegato: liver dumpling soup (Trentino).
zuppa frantoiana: the traditional olive harvest soup of Tuscany and Umbria, made by stewing a host of vegetables (kale, cabbage, leeks, pumpkin, potatoes, zucchini, herbs, parsley, basil, carrots, celery, onions, garlic, and fennel seeds) in extra-virgin olive oil, then adding beans and water
