Living here, it is almost a legal requirement to always have at least three types of ginger in the fridge / pantry. Young ginger, middle-aged ginger, old ginger, sand ginger etc. I covered what I can find in most stores here. I use some variety of it in almost everything. I also drink a lot of ginger tea, which I make from scratch.
But my favourite dish containing ginger is not Chinese. It is this. (The first recipe, of course. Never tried the others.) It calls for "syrup from a jar of stem ginger", which I've never seen here. So I have to make that myself, use the syrup and munch on the ginger at other times. I have cooked it many times and served to many friends, all of whom have loved it.
I also pickle my own young ginger - the sort of stuff served in Japanese sushi places as a between bites palate cleanser. Always have some in the fridge. It keeps forever; or would if I didn't keep eating it.
I also have some Chinese cooking wine laced with ginger. Seldom use it.
