Sinigang na Ulo ng Salmon: A Filipino Sour Soup with Salmon Head
Original name: Sinigang na Ulo ng Salmon (Salmon Head Sour Soup)

About this dish
Sinigang na ulo ng salmon is my lola’s answer to a cold day and a tight budget. The salmon head, with its collagen-rich cheeks and bones, gives the broth a deep, gelatinous body, while tamarind, tomato, and a handful of native vegetables turn it into a bright, savory-sour soup that sings.
I remember Lola would simmer the head whole, then ladle it over rice for us kids, saving the prized cheek meat for herself. It is a dish of resourcefulness and flavor, and it belongs on every Filipino table.

Method
Clean and prepare the salmon head
PT8MRinse the salmon head under cold running water. Remove any remaining gills and scales with a knife or your fingers. Cut the head into 4 manageable pieces. Pat dry with paper towels and set aside.
Sauté the aromatics
PT5MIn a large pot over medium heat, add a little oil. Sauté the onion, tomatoes, and ginger until the onion is translucent and the tomatoes are soft, about 5 minutes. This builds a flavorful base.
Add water and tamarind
PT10MPour in the water or fish stock and add the tamarind paste. Stir to dissolve. Bring to a boil, then lower the heat and simmer for 10 minutes to let the flavors meld.
Simmer the salmon head
PT10MGently slide the salmon head pieces into the pot. Simmer over low heat for 10 minutes. Do not stir vigorously; just let the fish poach in the sour broth. Skim off any foam that rises to the surface.
Add the vegetables

Tips
- For a clearer broth, blanch the salmon head in boiling water for 1 minute, then discard the water and start with fresh water. This removes impurities and reduces fishiness.
- Adjust sourness by adding more tamarind paste or a splash of calamansi juice at the end. Remember that sinigang should be pleasantly sour, not overwhelming.
- If you can’t find tamarind paste, use 2 tablespoons of tamarind powder or 1 cup of tamarind concentrate, adjusting to taste.
- Salmon head is rich in collagen, which gives the soup a lovely gelatinous texture. Simmer gently and avoid boiling hard to keep the meat tender.
Serving suggestions
- Serve hot over steamed jasmine rice.
- Pair with a side of fish sauce (patis) mixed with calamansi and chili for dipping.
- Add a sprinkle of crushed black pepper before serving.
- For a complete meal, serve with a simple cucumber and tomato salad.
