Tom kha kai is a traditional Thai soup known for its rich and aromatic flavors. It's made with coconut milk, chicken (kai), and galangal (kha) - a root similar to ginger that is common in Thai cooking. The broth is typically seasoned with lemongrass, kaffir lime leaves, and chili peppers, offering a perfect blend of spicy, sour, sweet, and savory flavors. It’s served as a starter or main course.
