Iga senyet is a traditional meat dish originating from Surabaya, but nowadays it's popular throughout the country. The dish consists of squeezed beef spare ribs and sambal sauce. In order to prepare the dish, beef spare ribs are cooked until tender with herbs such as lemongrass and galangal.
Coconut milk is added to the pan, and the ribs are shortly cooked until the coconut milk starts to boil. The spicy sambal paste is placed into a mortar, and the ribs are then placed on top and crushed with a pestle so that the meat becomes even more tender.
