For the filling:

1.Chop chicken, carrots, and potatoes into bite sized pieces, halve onions, set aside. In a mixing bowl combine heavy cream, cream of chicken and chicken stock; whisk to combine. Add all spices, chicken, and all vegetables; stir to combine. Transfer mixture to baking dish. See next steps to prepare crust.

For the crust:

1.Add flour and salt to a large mixing bowl. Cube cold butter. Either work the butter and shortening through the flour with a pastry blender/fingers or pulse these ingredients together in a food processor. Do this until mixture resembles coarse wet sand; you should be able to see tiny pieces of butter. Add the egg, vinegar, and cold water; mix (or pulse) to combine.

2. Turn the dough out onto a well floured surface and roll it out into a thin sheet. Add flour to the rolling pin as well. Once the dough meets the size of the pans your will use for baking, place the dough on top of the other prepared ingredients and get ready to bake! Pinch the dough to meet the sides of the baking dish so the liquid doesn't seep out. Use a fork to poke tiny holes on top to let the steam escape. Bake in the oven at 375 degrees for 1 hour.
