Rinse 1/2 cup of sticky rice and place it in a bowl. Cover with water and soak for at least 3 hours. Then, drain the rice.
In a large bowl, beat 1 egg. Mix in the minced ginger root, 2 teaspoons of soy sauce, and salt to taste.
Add 100 grams of ground pork, 2 tablespoons of cornstarch, and 1 tablespoon of pork stock to the egg mixture. Stir in one direction until combined, for about 5 to 6 minutes.
Roll the pork mixture into bite-sized balls.
Pour 1/4 cup of water into the bottom of a wok, enough to cover by about 1 inch. Bring the water to a simmer.
Roll the pork balls in the soaked and drained sticky rice until they are completely coated. Place 6 balls in a steamer basket.
Place the steamer basket in the wok and steam until the pork is cooked through and the rice is tender, about 30 minutes.
Remove the cooked sticky rice pork balls from the steamer and garnish with 1 teaspoon of goji berries.
