First, wash and soak a pack of dried bamboo leaves (it’s around 90 leaves) in water for 45 minutes to an hour until it’s soft.
Next, soak 10 cups of glutinous rice in a bowl for at least an hour. I normally soak it for 2 hours.
After that, soak 5 large dried mushrooms for 4-6 hours until it’s soft. (Most of the time, I soak it the night before I use it.)
The following, wash and soak 1 cup of small dried shrimp for 15 minutes. Drain well and set aside.
Also, wash and soak a small bag split no skin mung bean (10.58 oz or 300 g) for 30-45 minutes.
After soaking dried mushrooms, slice the soaked mushrooms into strips.
Put the sliced mushrooms in a bowl, add 2 tablespoons of oyster sauce and 1 tablespoon of sesame oil. Mix it well.
After, slice 3 pounds of pork into strips.
Marinate pork in a bowl by adding 3 tablespoons oyster sauce, 2 tablespoons soy sauce, 1 teaspoon garlic powder, 1 teaspoon salt, 1 teaspoon sugar and 1 tablespoon shaoxing cooking wine. Mix them well and let it marinate for at least 15 minutes. The best is to marinate it overnight.
Drain the water well after soaking glutinous rice. Then, add 1 tablespoon salt and 1 tablespoon vegetable oil. Mix them well.
Cut 8 salted egg yolks, each divide into 4 pieces.
Cut some strings into length, so it is easier for wrapping the rice dumplings.
Use 2 soaked bamboo leaves to fold them into a shape that can hold. Then, add some soaked glutinous rice, some soaked split mung beans, 1-2 pieces of marinated mushrooms, some soaked small dried shrimp, 1-2 pieces of marinated pork, 1 piece of salted egg yolk and cover some soaked glutinous rice.
After that, add a bamboo leaf and wrap them. Next, use a cut up string to tighten it. See detail in the video for how to wrap zongzi.
Put the wrapped sticky rice dumplings into an instant pot and fill up water about 85-90% to cover the rice dumplings. Close the lid and vent, push the manual button, adjust time to 45 minutes at high pressure and natural release.
