Pempek, mpek-mpek or empek-empek is a savoury fishcake delicacy from Palembang, Indonesia, made of fish and tapioca. Pempek is served with yellow noodles and a dark, rich sweet and sour sauce called kuah cuka or kuah cuko (lit. vinegar sauce).
Pempek is the best-known of Palembang's dishes. Its origin is undoubtly Palembang, however the history behind the creation of this savoury dish is unclear. According to local tradition, around the 16th century there was an old Chinese immigrant who lived near the Musi river. He noticed an abundance of fish caught by the local fishermen. In the Sumatran tropical climate, before the invention of refrigeration technology, most of these unsold leftover fish decayed and were wasted. The indigenous people, however had limited knowledge and techniques for processing fish. During that period, most of the indigenous people simply grilled, fried or boiled their fish instead of adding other ingredients to make new dishes. The old Chinese man mixed in some tapioca and other spices, which he then sold around the village on his cart. The people referred to this old man as 'pek-apek, where apek is a Chinese slang word to call an old man. The food is known today as empek-empek or pempek.
Another theory suggests that pempek was a Palembang adaptation of Southern Chinese ngo hiang or kekkian (fish slice) as a surimi (魚漿, yújiāng) based food. But instead of being served in soup or plainly fried, pempek is notable for its spicy palm sugar-vinegar based sauce.
