Savory Taiwanese Congee/Rice Porridge (Giam Mwe)

Taiwanese congee or rice porridge is usually cooked plain (just rice and water) or with some diced sweet potato, but another traditional version called "Giam Mue" (translated as "salty" rice porridge) includes savory ingredients like shiitake mushrooms, tiny dried shrimp, celery, fried shallots, and ginger. My mom makes a delicious version, but since I don't have her exact recipe, this is my take on it. I've gone off the rez a bit by adding ground pork but, hey, everything's better with pork, right?
