Arem-arem is an Indonesian-Javanese compressed rice cake in the form of a cylinder wrapped inside a banana leaf, filled with diced vegetables, tempeh, or oncom, and eaten as a snack. It is sometimes also filled with minced meat or abon (beef floss). Arem-arem is often described as a smaller size lontong with fillings, so it is sometimes also called lontong isi.
It is common in Java, and often found in Indonesian marketplaces as jajan pasar ("market munchies"), a type of kue (snack) offered there. Arem-arem is served at traditional ceremonies, family gatherings, birthdays or office meetings, and is often presented in a snack box. It is quite similar to lemper, but uses regular rice instead of sticky rice.
