What recipe do you use? I think "potato pancakes" sounds like a genius idea, but I have always found them disappointingly mushy. They sound crispy. They SHOULD BE crispy.
Was too lazy to go buy a pre-made pie crust from the store, so I mixed and rolled up my own using a new recipe. Cold butter, cold flour, ice water, and judicious pulsing in a food processor. Chilled the dough for the minimum 4 hours, rolled it out and built the pie. The filing is Christmas meat leftovers + veggies and a fat russet potato which has been lurking in the bottom fridge drawer. Used fresh-from-the-garden thyme, rosemary, and sage to season the filling and then instant mashed potatoes as a thickener. Could have left it in a bit longer, but it is delicious and will reheat well in the oven. The crimping is shameful:
