Steamed Garoupa With Soy Sauce

My hubby's 'second job' - fishing.  No, it is his hobby after he was 'banned' from playing badminton by his cardiologist after surviving a heart attack while playing the game. This is his catch of the day - a 1 kg Garoupa.  Very fresh fish that requires little 'dressing', so steaming it with a simple soy sauce mix and ginger with lots of spring onion/coriander should be awesome.
Ingredients

1 Garoupa fish [600 gm] - scaled and cleaned

1" piece ginger - shredded finely

1 stalk spring onions - cut fine shreds

1 stalk coriander - cut 1" length

1-2 tsp fried chopped garlic 

some oil [heated till hot] - optional
Sauce Ingredients

2 tbsp light soy sauce
1 tbsp oyster sauce

1 tsp sugar

5 tbsp water

1/2 tsp sesame oil

a dash of pepper

1. Steam fish over boiling water for 15 - 20 minutes or until fish is cooked.
2. Bring sauce ingredients  to a boil in a saucepan.  
3. Remove fish from steamer, drain away the stock if any.  Quickly pour sauce over steamed fish.
4. Garnish with shredded ginger, spring onions, coriander leaves and garlic crisps.
5. Lastly pour some hot oil over fish [optional] before serving immediately.

Note:

Definitely taste better with the extra hot oil but healthwise it is better to omit it after all this fish is very fresh.
