Thai Gaeng Som Recipe

Thai Gaeng Som is a traditional Thai sour curry known for its vibrant yellow-orange broth and wonderfully bold balance of sour, spicy, salty, and slightly sweet flavors. Unlike creamy Thai curries, Gaeng Som contains no coconut milk, allowing the tamarind and aromatic curry paste to shine.

This comforting Thai fish curry combines tender white fish with vegetables such as green papaya, long beans, and carrots. The light yet intensely flavorful broth makes it a refreshing choice for lunch or dinner, especially when served with steamed jasmine rice.

How to Make Thai Gaeng Som

1. Prepare the Curry Paste

Add dried chilies, garlic, shallots, lemongrass, turmeric, shrimp paste, and a little salt to a mortar or food processor.

Pound or blend until a smooth, aromatic paste forms.

2. Prepare the Tamarind Broth

Add water or fish stock to a large saucepan.

Stir in the curry paste and bring it to a gentle simmer.

3. Add the Vegetables

Add green papaya, carrots, and long beans.

Simmer until the vegetables begin to soften but still retain some texture.

4. Season the Curry

Stir in tamarind paste, fish sauce, and palm sugar.

Taste and adjust the balance until the broth is pleasantly sour, salty, spicy, and slightly sweet.

5. Cook the Fish

Gently add the fish pieces to the simmering curry.

Cook until the fish is tender and flakes easily.

Avoid stirring aggressively so the fish remains intact.

6. Finish and Serve

Taste the curry once more and adjust the seasoning if necessary.

Serve warm with steamed jasmine rice.

Tips for Perfect Thai Gaeng Som

• Use firm white fish that won't easily fall apart.
• Fresh tamarind paste gives the best sour flavor.
• Add the fish near the end so it doesn't overcook.
• Adjust tamarind and palm sugar gradually to achieve the right balance.
• Keep the curry broth relatively light rather than thick.
• Don't stir the fish too much after adding it.
