In the past, berries were consumed instead of candies, from this fact they have become in many ways proverbial, synonymous with trifles. The term "jujube" refers to a naive person. The expression "to go in jujube broth" refers to an almost forgotten recipe that created a real delicacy.
Jujube (Ziziphus jujuba Mill.) Is a fruit tree belonging to the Rhamnaceae family [2] and to the genus Ziziphus, also known as Chinese date, natsume or tsao (simplified Chinese: 枣; traditional Chinese: 棗; pinyin: zǎo) . The fruit is commonly called jujube (plural: jujube, in italian it's one of the few words that switches gender from singular to plural).
