In the bowl of a food processor or by hand in a large bowl, combine flour, sugar and salt.
Add cubed, cold butter and pulse several times or cut in with a fork or pastry mixer until it resembles coarse crumbs.
Add in ice water a bit at a time and mix until a ball can be formed or dough begins to hold together.
Turn out to a lightly floured surface and gather together into a ball. Cut into 2 even pieces, press into discs, wrap in plastic and chill for at least 30 minutes.
Remove both discs from the fridge and let them sit for 20 minutes. Remove plastic and roll both discs out onto the surface. Transfer both to their own 9" pie dish and flute edges.
Place eggs in a medium bowl and beat lightly. Add brown sugar, whole can of Pure Pumpkin (796ml), pumpkin pie spice and salt. Stir ingredients together until well combined. Blend in heavy cream or evaporated milk. Pour filling evenly into each prepared pie shell.
Bake both pies together at 425°F (220°C) for 15 minutes. Reduce oven temperature to 350°F (180°C) and continue baking 35-45 minutes longer or until knife inserted 1-inch from the crust edge comes out clean and filling is almost set in the centre. Cool on hour and serve.
