instead of mixing in a mixer , mash them by hand might help them keep some of the starch in tact and help them hold together, and why do all the prep the day before, what about scooping out the potato while its hot, mash it , add a little butter and milk, some things llike scallions, or onions, a little garlic maybe and mash it , then put in a bowl and fill the potatoes with it the next day if you must do it the day before, but IMO they taste sooooo very much better if you do it all on the same day , and it doesnt take long to do them all fresh with a better end result |
