Sambal Udang is a lovely Penang Nyonya dish, comprising of prawn cooked in fiery sambal and tamarind. Marinating some tamarind with enough water to make a thick, creamy gravy for the dish is fairly important. The Nyonyas love their prawns either cooked in tamarind like Assam prawns or as a spicy and creamy dish. The Sambal Prawn is served together with plain hot rice or nasi lemak (coconut milk rice). There are many variations of Sambal Udang, but the basic ingredients are more or less the same.
