Prepare the dried goods

Dried ingredients

You would need to prepare all the dried goods like dried oysters, dried shiitake mushrooms and dried scallops prior to use.

Dried Oysters

1/  Soak the dried oysters in cold water for 10 minutes or more until they are softer, then rub gently with your fingers to get rid of dirt and sand. Remove and discard the hard muscles. Rinse well with water, drain and dry thoroughly with a clean towel.

Tip: Drying helps to prevent splatter when you fry the oysters with oil. So dry it as much as you can.

2/ Marinate the hydrated oysters with salt, sugar, ginger juice, wine, cornstarch and oil.

Soaking the mushrooms and black moss

Dried Scallops

Steaming the dried scallops

3/ Steam the washed dried scallops until soft. Shred and leave for later use

Dried Shiitake Mushrooms

4/ Wash and soak the dried mushrooms until soft and plump. Take out from the soaking liquid and wash the hydrated mushrooms. Leave aside for later use.

Tip: Filter and do not discard the soaking liquid. You may use it for adding liquid to the braising sauce for added flavours.


Frying the oysters until golden

1/ Heat up a heavy, flat-bottomed frying pan, add 1 tbsp oil, and when hot, fry the ginger and spring onion until fragrant. Now sear the dried oysters in this oil until golden brown.

Tip: You may also use a claypot like I did to do everything in it. Claypot are perfect for braising as it keeps a constant temperature anddoes not dry up as quickly.

2/ Sizzle in the two types of wine(Shaoxing and rose wine, then splash in the chicken stock and water. Transfer the oysters and sauce into a braising pan. If you use a claypot, just proceed to the next step.

Caution: Do not use a non-stick pan for braising.
Add chicken stock and scallops

3/ Add the shredded dry scallop, and add oyster sauce, dark soya sauce, sugar and salt to taste. Bring to a boil, lower the heat to a fast simmer, covered, for 1 hour, replenish with water if necessary.

Tip: Remember to check the braising liquid, never let it dry up.
Add the rest of the ingredients

4/ Add the roast belly pork pieces, mushrooms and continue to braise with the oyster for 30 minutes; add more liquid if necessary, make sure there remains 1 cup of liquid at the end of cooking. Drain the sauce and set aside.

Assembling the dish

5/ Arrange oysters at the bottom of a deep bowl, then a layer of roast pork, a layer of mushrooms and finally cover with dark moss. Pour the drained sauce into the bowl and steam for 20 minutes.

Tip: Depending on the amount of braising liquid you have left, you may want to only return part of the sauce as the base for steaming the final assembly.
Final steaming

6/ After the oysters are soft, drain the sauce from the steamed bowl into a wok. Bring the sauce to boil and thicken with cornstarch mixture. Sizzle in sesame oil.

7/ Place a plate over the bowl and invert the oysters, mushrooms etc. onto the plate. Be sure to hold the plate and bowl firmly together. Lift and remove the bowl.

Drizzling the thicken sauce

8/ Pour the sauce over it. You may serve it over a bed of blanched Chinese lettuce or steamed broccoli.
