*I mashed my potatoes with a little bit of Greek yogurt and half-and-half to make them a little creamier.
*Filling the pierogi is easier with a stiff mixture – if you have time, pop the filling into the fridge for an hour or two, or even better, make the filling a day ahead and refrigerate overnight.
*Mashed potato pancakes – add an egg to the mashed potato mixture and a couple of tablespoons of flour – up 1/4 cup if you have a lot of mixture left. Mix it all up, form into pancakes and brown on both sides in a pre-heated skillet with oil.
