• Mise en Place
  

For the filling

• 2 lbs Apple
  If you have an apple peeler/corer, and it has a slicing function, use that to peel, core and slice the apples. If not, peel the apples, core them, and slice them thinly.
  
• 1/4 cup Brown sugar, 2 tablespoon Raisins, 1 teaspoon Cinnamon, 1 teaspoon Mace, 1 tablespoon unsalted butter
  Mix the ingredients for the filling together in a large bowl. Cover the bowl and set it aside.

For the Crust

• 2 tablespoon Cheddar cheese powder, 4 tablespoon Cinnamon, 1 teaspoon Nutmeg
  Mix the powdered cheese, cinnamon, and nutmeg in a small bowl. Taste for seasoning. If it tastes too much like cheese, add more cinnamon. Open the duster and dip it into the powder. Set it aside.
• 12 sheets Phyllo dough, 3 tablespoon unsalted butter
  Brush the pie plate with some butter. Lay a sheet of phyllo on the butter and push the phyllo down, so it sticks to the pan. Cover the remaining phyllo with a damp dish towel, so it doesn't dry out.
  
• Dust the layer with some of the cheese mixture.
  
• Add another layer of phyllo at a 10° angle to the first layer. Push it down, brush it with butter, and dust it with the cheese mixture. Continue turning each layer another 10° until you have gone all around the pie. You will have phyllo sheets left over, which you will need to make the Pi sign.
  
• Put the filling in and try to flatten the top a little where the Pi is going to go.
  
• Bring the sides of the pastry up and bend it over the filling, brushing the layers with butter as you go. Some will have dried out, so brush them and then fold them over.
  
• When that is done, dust the rim with the powder.
  

For the π

• 2 sheets Phyllo dough, 2 teaspoon Black sesame seeds
  To make the Pi shape, use three or four layers of phyllo and cut it with a very sharp knife. Cut two long pieces about 1/2" wide and 3" long. Make the top piece about 1.2" tall and 3" wide. Separate the cut pieces and lay them in the Pi shape brushing butter on each layer. Finally, butter the top layer and using the fingers, carefully spread the black sesame seeds on the Pi layer.
  
• Bake the pie at 350 °F (177 °C) for about 30 minutes or until the apples soften and the phyllo browned. Let the pie cool before cutting. Enjoy! Happy Pi Day!
