Heat up a pot of water to boiling. Remember to add some salt to the water. Peel the potatoes and chop into even pieces then boil the potatoes until tender. Before straining the potatoes, save 1/2 cup of the potato water. Strain the potatoes and mash them up roughly.
In a large frying pan or skillet, cook the onions, garlic, beef and pork over medium to high heat until it's no longer brown.
mix all the spices into a small bowl, then add them to the meat mixture, mix the spices.
add the potato water and continue to simmer until all the water has evaporated mixing quite a bit through the process.
Add the mashed potatoes and mix everything together
Preheat the oven to 400°F while you make the pie.
Remove the pastry dough from the fridge and lightly flour a wood cutting board or counter-top surface. Cut the dough disc in half and roll out the first half to about 1/8 inch thick disc. Then lay the dough over your pie baking pan. Add the meat filling.
Take the remaining dough and roll it out into another disc and lay on top of the meat pie. Now, raise your fist in the air and call upon the powers of Gordon Ramsey to electrify your fluting ability.
Cut some slits into the top of the pie any way you want. We tried to put HDND because I'm super creative and artistic...as you can tell.
Brush the top of the pie and all around the edges with the egg wash. Throw it in the oven and bake for 30-35 minutes. After it's done let it sit for about 10 minutes before serving.
Don't worry if it falls apart when getting it out of the pie. I probably should have pressed in the meat and maybe it would have held together better.
