Mum's Irish Apple Pie

Step 1
Preheat oven to 350 degrees F (175 degrees C). Grease a 9 inch pie pan.

Step 2
To Make Crust: In a large bowl, combine flours, salt and sugar. Cut in butter and shortening until coarse crumbs are formed. Mix in sour cream and lemon juice. Keep mixing until dough forms a ball; dough may be slightly lumpy, this is fine. Wrap dough ball in plastic wrap and allow to chill for 1 hour.

Step 3
Once chilled, take dough out of refrigerator and cut it in half; keep one half covered and in the refrigerator. Roll dough to 1/8 of an inch. To lift pie shell, roll dough around rolling pin and then unroll into pie pan. Trim overhanging edges of pie crust.

Step 4
To Make Filling: Place apples into pie shell. In a small bowl, combine sugar, flour and nutmeg; mix thoroughly. Sprinkle mixture over apples. Squirt lemon juice over apples. Place pie in refrigerator while top crust is rolled out.

Step 5
Remove pie from refrigerator. Brush outer edge of bottom crust with beaten egg. Place second crust on top of pie; crimp pie shell edges together. Brush entire top crust with egg and cut 4 steam slots into it.

Step 6
Bake in a preheated 350 degrees F (175 degrees C) oven for 45 minutes, or until golden brown. Allow pie to completely cool before serving. Serve warm with whipped cream or vanilla ice cream.
