Rempeyek
Rempeyek or peyek is a deep-fried savoury Indonesian-Javanese cracker made from flour (usually rice flour) with other ingredients, bound or coated by crispy flour batter. The most common type of rempeyek is "peyek kacang" ("peanut peyek"); however, other ingredients can be used instead, such as "teri" (dried anchovies), "rebon" (small shrimp), or "ebi" (dried shrimp). Today, rempeyek is commonly found in Indonesia and Malaysia, as well as in countries with considerable Indonesian migrant populations, such as The Netherlands and Suriname. Coconut milk, salt, and spices such as ground candlenut and coriander are often mixed within the flour  batter. Some recipes also add a chopped citrus leaf. The spiced batter, mixed or sprinkled with the granule ingredients, is deep fried in hot coconut oil. The flour batter acts as a binding agent for the granules (peanuts, anchovy, shrimp, etc.). It hardens upon frying and turns into a golden brown and crispy cracker. In Indonesia, rempeyek making is traditionally a small-scale home industry, yet today some rempeyek producers have reached a larger production scale and distribute widely with a rempeyek-brand trading value reaching 25 million Rupiah (around US$2,100) monthly. In Malaysia, rempeyek now is widely made  using machines. Etymology and origin. "Rempeyek" is derived from the Javanese onomatopoeia "peyek", depicting the sound of a crisp cracker breaking. Rempeyek is often associated with Javanese cuisine, served to accompany pecel (vegetables in peanut sauce) or other meals meal, or as a stand-alone snack. Today, it is common throughout Indonesia, and is also popular in Malaysia following the migration of Javanese immigrants in the early 19th century. Variants. The most common and widely distributed type of rempeyek is "rempeyek kacang" (peanut rempeyek); however, anchovy, small shrimp, dried shrimp, spinach ("rempeyek bayam"), and beans such as mung beans and  soybeans are also common types. "Rempeyek kacang" is especially common in the Banyumas region of Central Java, while "rempeyek rebon" (small shrimp) is common in the Javanese port town of Cirebon. Rempeyek made with larger shrimp are commonly found in Padang restaurants. More niche variants with insect ingredients, such as crickets and termites, also exist. In popular culture. A popular Javanese song, "Iwak Peyek", by female dangdut group Trio Macan, describes "rempeyek" as a commoners' dish. It served as the rallying song for supporters of Persebaya football club from Surabaya, East Java.
