Sup Iga Sapi is a hearty and delicious Indonesian beef short rib soup with melt-in-your-mouth slow-cooked short ribs and vegetables simmered in a warm savory broth. It will hit the spot when you are craving a comforting soup.
Clean ribs – Boil ribs in 4 cups (1 liter) water for 5 minutes until foamy and the scum has surfaced. Transfer the ribs into a separate bowl and discard the water. Rinse the ribs with clean water.
Boil ribs – Add the cleaned ribs, 6 cups (1.5 liter) water, nutmeg, and the white part of green onion into a pressure cooker. Season with salt, beef stock powder, and ground white pepper. Heat on medium-high heat until shimmering. Seal the pressure cooker, bring to high pressure, and cook for 20-30 minutes. Depressurize the pressure cooker and remove the lid. Check if the ribs are tender. If the ribs are still tough, you need to cook them longer. (If you don't have a pressure cooker, you can simmer the ingredients in a large pot for 1 hour or more until the ribs are tender)
Fry aromatics – In a small frying pan, heat oil on low-medium heat. Once the oil is hot, add the garlic and shallots. Stir fry until they turn brown. Transfer them to the soup.
Add carrots and potatoes to the soup. Bring the soup to a boil and simmer for 15-20 minutes until the carrots and potatoes are tender.
Add the green part of green onion and leaf celery. Taste the soup and adjust the seasonings. Remove from the heat.
How to serve –Place some tomato chunks in serving bowls. Add the beef rib soup. Squeeze a little bit of lime juice over the soup if you want to add tanginess. Serve the soup with steamed rice.
