In Indonesia, among the Javanese, rujak is an essential part of the traditional prenatal ceremony called tujuh bulanan (literally: seventh month).
The ritual was meant to wish the mother-to-be a safe, smooth and successful labour.
Special fruit rujak is made for this occasion, and later served to the mother-to-be and her guests, primarily her female friends.
It is widely known that the sweet, spicy and sour tastes of rojak are adored by pregnant women.
The recipe of rujak for this ceremony is similar to typical Indonesian fruit rujak, with the exceptions that the fruits are roughly shredded instead of thinly sliced, and that jeruk bali (pomelo/pink grapefruit) is an essential ingredient.
It is believed that if the rujak overall tastes sweet, the unborn would be a girl, and if it is spicy, the unborn baby is a boy.

Mangarabar, or rujak making, is a special event for the inhabitants of the Batak Mandailing region in Tapanuli, North Sumatra, Indonesia after the harvest.
Normally the whole village will be involved in making and consuming the rujak.

In Malaysia and Singapore, the term "rojak" is also used as a colloquial expression for an eclectic mix, in particular as a word describing the multi-ethnic character of Malaysian and Singaporean society.
