The main ingredient in a traditional green curry is green curry paste, which is primarily made from fresh green chilies. This paste provides the distinct flavor and color to the dish and typically includes ingredients such as lemongrass, galangal, garlic, shallots, and kaffir lime leaves. The spiciness can vary based on the number and variety of chilies used. Green curry is a staple in Thai cuisine, often cooked with coconut milk, vegetables, and protein sources like chicken or shrimp. The combination of aromatic herbs and spices results in a rich, flavorful curry that is well-loved worldwide.
