Preheat the oven to 375 degrees.
Boil and slice the eggs.
Pare and slice the potatoes, apples and onions. Slice everything ¼ inch thick.
Place the apples and potatoes in a bowl of water to prevent oxidation.
Roll out the bottom crust and set it into the pie pan.
Mix the salt, pepper, nutmeg and mace together in a single bowl.
Drain and dry the apples and potatoes with a towel.
Begin the layers from the bottom up with potatoes, then eggs, then apples and then onions.
Sprinkle each layer with a little of the seasoning and little bits of butter.
Continue filling and seasoning the pie until you are out of ingredients.
Put a top crust on the pie and crimp the edges.
Cut 4 or 5 slashes on top crust to allow steam to vent out.
Bake for 45-50 minutes or until the crust is a nice golden brown.
