It usually only takes a few minutes to mash potatoes. Be very careful never to over mash your potatoes, as they can become gluey and unpleasant. I just use a simple potato masher, but in a pinch a fork will work. Some folks swear by a handheld mixer but again, just be careful not to over mash. I like to do an initial mash, add a bit of the boiling water or a little vegan butter, a little sea salt and maybe a little garlic. Then mix it and it should be mashed enough--I don't like mine super smooth.
