Sayur Asem is a traditional Indonesian sour vegetable soup known for its refreshing and tangy flavor. It typically consists of a variety of vegetables such as young jackfruit, long beans, corn, melinjo leaves and seeds, and sometimes peanuts or chayote. The sourness comes from tamarind juice, which gives the soup a distinctive bright and slightly tart taste. Sayur Asem is often seasoned with garlic, shallots, and sometimes chili for a mild spiciness. It is a popular dish served as a side to accompany rice and grilled or fried fish, making it a wholesome and light meal perfect for hot weather.
