Separate the salted egg yolks from the whites. Save the salted egg whites for other use, don't throw them away
If you plan to use zucchini, peel and cut into 1-inch ring and then cut into quarters. Set aside
Prepare the meat patty:
It is best if you can have some fat in the meat. Cut this into smaller pieces and ground it in your food processor, or finely mince the meat with cleaver
Add the seasonings and stir in one direction to combine so the mixture resembles sticky paste
Bring a small pot of water to a boil. Cook a tiny portion of the meat paste so you can have a taste. Add more salt or any seasonings to suit your preference. This is the only chance you have to adjust the seasonings before you steam the meat patty.
Steaming:
Transfer the pork mixture into a steaming plate. Use your wet palm to pack the meat down and to smooth the surface to form giant pork patty. Arrange the half salted egg yolk on top
Bring the water in the steamer to a boil. Steam the pork patty on high heat for 15 minutes or until the pork is cooked through. 5 minutes before end of cooking time, arrange the zucchini around the edge and continue steaming
Serving:
Serve the dish while it's warm as part of multi-course meal with plain cooked rice
