Sayur Asem (Indonesian Tamarind Vegetable Soup)

About This Recipe

Sayur asem is a West Javanese vegetable soup built entirely around the sour-savory punch of tamarind, a flavor that shows up across Indonesian cooking the way lemon shows up in Mediterranean food. It's a market-day soup, traditionally made with whatever vegetables are in season -- unripe jackfruit, corn on the cob, long beans, chayote -- simmered in a light tamarind-galangal broth until everything is tender but still distinct. The technique is simple but the order matters: the tamarind broth and aromatics (galangal, bay leaves, candlenuts) go in first to build the sour base, and the vegetables are added in stages according to how long they take to cook, so the corn is just tender when the leafy greens have barely wilted. A handful of raw peanuts simmered from the start adds body and a faint nuttiness to the broth. Sayur asem is almost always served with rice and something fried -- tempeh, fritters, or fried fish -- since the soup itself is light and sour rather than rich. It's the kind of dish that tastes better the more genuinely sour and fresh the tamarind is, so using real tamarind pulp rather than concentrate makes a real difference.

Variations

• •

  Sayur asem Jakarta style adds peanuts and a touch more sugar for a milder sour profile.

• •

  Add a piece of smoked or dried fish to the broth for extra depth.

• •

  Make it vegan by skipping fish and relying on candlenuts and peanuts for richness.

Storage

Refrigerate up to 2 days; the greens will lose some texture but the broth stays good. Reheat gently on the stove, not the microwave, to avoid overcooking the vegetables further.
