Kerupuk ikan is a traditional Indonesian snack made from fish and starch. It is typically prepared by mixing ground fish with tapioca flour, spices, and salt, then shaping the mixture into thin sheets. These sheets are dried and later sliced into small pieces before being fried until crispy. This crunchy treat is often enjoyed as a side dish or snack and can be found in various flavors, depending on the type of fish used. Kerupuk ikan is popular in many regions of Indonesia and is commonly served with rice or as a topping for soups and salads.
