Herbal steamed fish

I like herbal as well as fish. Thus, this is what I would like to try -- herbal steamed fish. :)

Ingredients:

½ tsp salt
¼ tsp pepper
200ml water
Herbs
3 slices (5g) tong kwai
10g hair of ginseng roots (yong sum soe)
4g chuen koong
1 tbsp kei chi
3 red dates, halved
3 slices ginger
Seasoning
½ tsp salt
½ tsp light soy sauce
½ tsp sugar
1 tsp sesame oil

1. Clean fish and make two diagonal cuts on either side of the body. Marinate with salt and pepper for 10-15 minutes.
2. Rinse the herbs and combine with seasoning and water. Cook over low heat, and simmer for 20 minutes.
3. Pour the cooked herbal stock and put a little of the herbs over the fish. Steam over rapidly boiling water for 15 minutes. Serve immediately.
