The sweet and sour flavour of this dish is considered refreshing and very compatible with fried or grilled dishes, including salted fish, ikan goreng, ayam goreng and lalapan, a kind of vegetable salad usually served raw but can also be cooked, and is usually eaten with steamed rice and sambal terasi chili paste.
Common ingredients are peanuts, young jackfruit, young leaves and unpeeled seeds of melinjo, bilimbi, chayote, and long beans, all cooked in tamarind-based soups and sometimes enriched with beef stock. Quite often, the recipe also includes corn.
Several variations exist including sayur asem Jakarta (a version from the Betawi people of Jakarta), sayur asem kangkung (a version which includes water spinach), sayur asem ikan asin (includes salted fish, usually snakehead murrel), and sayur asem kacang merah (consists of red beans and green beans in tamarind and beef stock). The Karo version of sayur asem is made using torch ginger buds and, more importantly, the sour-tasting seed pods. Sayur asem rembang is a vegetable soup with a sour flavor.
