Sambal Udang : Spicy Prawns - whole prawns or shrimp are cooked in a classic Malay sauce; a spicy robust sauce made with chilies, shallots, garlic, stewed tomatoes, tamarind paste and belacan [also spelt belachan or blacan], a dried shrimp paste paste. Sambal Udang is the perfect accompaniment to the country's un-official national dish - Nasi Lemak.
