Plural of fondue; multiple dishes where foods are cooked or dipped in communal pots of melted cheese, chocolate, or oil.
From 'fondue' (from French 'fondu,' past participle of 'fondre') plus the regular English plural '-s'. The English word entered usage in the 20th century as the dish became fashionable.
Fondue became hugely popular in English-speaking countries in the 1960s-70s, which is quite recent for a word to arrive and become commonplace—showing how food trends create new vocabulary bubbles that sometimes fade (remember how everyone had fondue sets?) and sometimes stick around.
