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