The ingredients are not mixed together, use a tablespoon of seasoning for the mushrooms, and the rest for the pork.
So, in separate containers, you have rice, pork, chestnuts, mushrooms, dried prawns, salted eggs and fried shallots.
Set the water to boil in a pressure cooker before you start wrapping the dumplings. The water must be oversalted and add a tablespoon or two of oil to it.
When you gather the dumpling, put a tablespoon of rice in first, then sprinkle some shallots, 1 piece of pork, 1/2 mushroom, 1 piece of dried prawn, 1 piece of chestnut, 1/2 salted egg yolk, sprinkle a few red beans if using. Top off with rice and then wrap up.
Fully submerge the dumplings in the boiling water, add a tablespoon of oil to the water and then cook for 30 minutes under high pressure.
Drain the water completely when dumplings are cooked.
This recipe makes 20 huge dumplings. Enjoy!
