Thai cuisine often blends aromatic herbs, citrus, and chilies with rich coconut or butter bases. While cod is not a traditional Thai fish, the technique of cooking seafood in a fragrant green curry butter reflects the Thai love for balancing heat, sour, salty, and sweet flavors, especially in coastal regions where fish and shellfish are abundant.

In Southern Thailand, green curry seafood often uses coconut milk and fresh turmeric, while Central Thailand may incorporate a butter‑based sauce like this recipe. Some regions add kaffir lime leaves or galangal more heavily, and the choice of seafood can range from shrimp to snapper.

It is typically served hot, plated over steamed jasmine rice or alongside flat rice noodles, and garnished with fresh herbs, sliced chilies, and a squeeze of lime to brighten the rich butter sauce.

Seafood dishes like this are popular for festive gatherings, family celebrations, and coastal festivals where fresh fish and clams are plentiful. The bright colors and balanced flavors make it a centerpiece for holiday meals and special occasions.

Authentic ingredients include lemongrass, galanga, Thai green chilies, fish sauce, lime juice, and fresh herbs like Thai basil and coriander. Substitutes can be ginger for galanga, jalapeño for green chilies, and soy sauce with lime for fish sauce if needed.

Common errors include over‑cooking the cod, using cold butter which leads to a grainy sauce, not seasoning the clams enough, and letting the butter sauce separate by adding it too quickly or at too high a temperature.

Butter provides a rich, silky mouthfeel that complements the briny clam juices and the delicate cod, while still allowing the bright aromatics of lemongrass and galanga to shine. Coconut milk would add sweetness and a thicker texture, changing the intended flavor balance.

Yes, you can prepare the green curry butter paste and the chili‑lime dressing up to 24 hours ahead and keep them refrigerated. Cooked cod and clams are best served immediately, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days and reheated gently.

The cod should be opaque, flaky, and slightly springy to the touch. The clams should be open, releasing a fragrant broth that mixes with the butter sauce. The roasted tomatoes should be blistered and caramelized, and the sauce should be glossy, not oily.

The YouTube channel Big Has focuses on bold, outdoor‑style cooking demonstrations, often featuring wood‑fire techniques, seafood, and vibrant Asian‑inspired flavors presented in a casual, energetic format.

Big Has emphasizes high‑heat, wood‑fire or very hot oven methods and combines traditional Thai aromatics with Western butter‑based sauces, creating a fusion style that is more rugged and fast‑paced than the meticulous, step‑by‑step approach of many classic Thai channels.
