Season a cod fish steak with salt and white pepper. Place in a shallow dish and place the dish in a bamboo steamer over a wok. Steam until the fish flakes easily with a fork.
Fry up some chopped garlic until brown and crispy. Make a sauce from soy sauce and sesame oil. Mince up some cilantro and green onions. Remove the dish from the steamer, sprinkle with fried chopped garlic, drizzle on the sauce, then garnish with the cilantro and green onions.
