Rujak tumbuk or rujak bēbēk is a traditional fruit salad originating from Indonesia. This type of rujak uses the same ingredients as for the basic fruit rujak (rujak buah) such as Java apples, kedondong (June plums), unripe mango, green pisang batu banana, jicama, and red yam.
The fruit is mashed or ground with a wooden mortar, while the dressing is added to the mix instead of being poured over the top. It's typically made with a combiantion of palm sugar, chili peppers, salt, and prawn paste. This rujak is traditionally served in individual small plastic cups or on banana leaf plates.
