Add the oil to a hot wok. Once shimmering, add the dried shrimp, garlic, and mushrooms and cook until browned.
Add the sausage and fry until brown.
Add the cubed squash and gently stir-fry 1 minute, then deglaze the pan with the rice wine.
Add the glutinous rice and stir-fry 5 minutes.
Add the soy sauce, soy paste, black sesame oil, stock, salt, and white pepper. Stir in the scallions and fried shallots, incorporate, and turn off the heat.
Transfer the mixture to a steamer pot. Steam for 45 minutes to 1 hour.
Let sit 10 to 15 minutes in the residual steam before opening. Taste to be sure the grains are cooked; if needed, add a splash of water and steam 10 to 20 minutes longer.
