Prior to beginning, gather all ingredients and utensils you'll need. Make sure all the ingredients are cold. I do that by sticking everything in the fridge over night (or in the freezer for 30 minutes) prior to preparing the dough. Cutting the shortening and butter up into small chunks prior to chilling it, will help you with working with it immediately. You want the fat to stay as cold as possible.
Add flour, salt, sugar into a food processor and mix together shortly. Add butter and shortening and pulse until crumbly. (Works best pulsing in 1- to 2-second bursts until most of the fat is the size of peas). If you don't have a food processor, mix everything quickly with a fork in a bowl.
Once everything is crumbly add the iced water to the food processor/bowl. Pulse until dough begins to clump into small balls. Don’t allow the dough to become completely one single mass during processing! This is necessary to get that flaky pie crust texture. You want the dough to hold together, but you’re not making bread or pizza dough.
Gently press the dough together with your hands. If it does not hold together, you may need a bit more ice water. Divide the dough in ⅔ and ⅓. Press each piece into a round flat disk (wrap in plastic wrap, parchment, wax paper or put into an airtight container). Chill for at least 30 minutes*. While the dough is chilling you can prepare the filling.
In a mixing bowl combine all ingredients for the filling and whisk together. Either with an electric hand or stand mixer, or by hand with a whisk. Once everything is well combined, set aside. If necessary close the bowl with its lid, or wrap with plastic wrap/wax paper.You don’t want clumps of starch or of spices in there! Make sure to sieve the starch into the filling mixture to prevent clumps and to mix everything thoroughly.
Once the dough is chilled, take out the bigger part and roll it out on a lightly floured surface. This will be our shell. Make sure you have enough space when rolling it out! You can either roll it out on your clean countertop or on a pastry board.
Place the dough in the center of the floured surface and flour the top of the dough as well. Sprinkle the chilled rolling pin with some flour as well. With uniform pressure on the pin, roll the dough from the center out in all directions. Try keeping the dough in a circular shape. Rotate the dough itself rather than by moving the pin. Periodically, make sure the dough isn’t sticking to the work surface by sliding your hand (or a pastry scraper/spatula) beneath it and sprinkling some flour on the counter, if necessary. It can be tricky but try not to use too much flour, or the crust could turn dense and chewy, instead of light and flaky.
Roll the dough 5 – 6cm (2,5 inches) wider than your pan so you will have plenty of dough for covering the entire pan and for creating a rim (if wanted). Gently place your pan upside down in the center of the dough for calculating the width.
Once rolled out transfer the dough to your pan: roll it loosely around your rolling pin. Center the pin over one side of the pan, and then gently unroll the dough. Patch any holes or cracks with dough scraps by first lightly moistening the scraps with cold water. When the dough completely covers the pan, trim the edges with scissors. Put the prepared pie crust pan in the fridge until ready for filling and baking.
Get out the other chilled piece of dough and roll out, just like before. You can either cut out even strips and make a lattice top, you could braid some of the strips or simply cut out pieces with cookie cutters/pie crust cutters of your choice. I rolled out the dough into a big circle and cut out parts with fall themed leaf pie crust cutters. Once cut out I put them on an even surface and then back into the fridge (or shortly in the freezer) to chill. When the cutouts are chilled they are way easier to handle!
Preheat your oven to 180°C / 355°F.
Pour your prepared filling into your (pre-baked) pie crust. Get out the chilled lattices or cutouts. Top your pie with your favorite pastry design; or leave uncovered. It’s important that the pie goes into the hot oven as soon as possible or the filling will begin to soften the bottom crust.
Bake for about 30-40 minutes, or until the crust is lightly browned and the outermost of the filling is set. If the edges of the pie are browning too much during baking, cover with pie crust shield. Don’t worry if the center is still a bit soft; it continues to firm up as the pie is cooling down.
Turn off the oven, and leave the pie in the oven for another 15 minutes.This helps everything to set properly. Take the pie out of the oven, and allow it to cool fully on the counter before slicing. Enjoy! Tastes great with some toasted nuts (like pecans or walnuts) and plant based whipped cream, vanilla ice cream or yogurt on top.
