Step 1 Prepare the rice: In a large bowl, rinse the rice under cool running water, gently swirling it with your hands until the water runs clear. Shut off the water, and leave the rice to sit in the water for 2 hours, then drain the rice, leaving it in the bowl.
Step 2 Meanwhile, in a medium bowl, soak the mushrooms in enough water to cover until softened, about 45 minutes. Drain the water (dispose of it, or save the liquid for another use), discard the stems and dice the mushrooms. Set aside.
Step 3Rinse the dried shrimp, then place them in a small bowl. Soak the shrimp in enough water to cover until softened, about 5 minutes. Drain the shrimp.
Step 4Pour the 6 cups of boiling water over the drained rice to cover. Set the rice aside for 15 minutes, then drain the rice again.
Step 5In a large nonstick wok or a large pan with fairly high sides, heat the oil over medium heat until hot. Add the garlic, sausage, mushrooms and shrimp. Saute, stirring frequently, until the sausage and shrimp are lightly caramelized and the garlic is very fragrant, several minutes. Add the rice and stir to thoroughly combine.
Step 6Stir 3 to 4 tablespoons of chicken broth in with the rice, then cover and cook for 3 minutes. Uncover and repeat until the rice is soft and sticky (similar to cooking risotto); you may not use all of the chicken broth.
Step 7Season to taste with the soy sauce and the white pepper, stirring to combine and marry the flavors. Serve immediately.
