Lontong Kupang Sidoarjo
Lontong Kupang is a unique and flavorful traditional dish from Sidoarjo, East Java,
Indonesia. It features kupang (tiny sea clams) cooked in a savory broth and
served with lontong (rice cakes), lentho (fried mashed cassava and black-eyed
pea patties), fried garlic, and spicy petis sauce (a thick, sweet fermented shrimp
paste condiment).
This dish is especially popular in coastal regions and is known for its bold umami
flavor. Lontong Kupang is typically enjoyed as a light lunch or afternoon meal,
often served warm with a squeeze of lime and optional chili. The combination of
chewy rice cake, soft clams, crunchy lentho, and rich petis makes it a memorable
culinary experience.
Ingredients:
For the Kupang Broth:
300 grams of kupang (tiny sea clams), cleaned and rinsed
3 cloves of garlic, minced
2 bay leaves
2 cm of galangal, crushed
1 stalk of lemongrass, crushed
750 ml of water
1/2 teaspoon of salt
1/2 teaspoon of sugar
1 tablespoon of cooking oil
For the Side Components:
2 pieces of lontong (rice cakes), sliced
2 pieces of lentho (cassava-black-eyed pea fritters)
1 tablespoon of fried garlic
2 tablespoons of petis udang (shrimp paste sauce)

Tips:
Use fresh kupang and soak them in clean water to remove any sand or
grit.
You can find petis at Indonesian or Asian grocery stores; choose the thick
and black variety for authenticity.
