The time needed: pastry crusts 1 hour, filling 15 minutes, baking 50 minutes.
In a large bowl, measure and pour flour and cut lard, use fingers to break and mix together till evenly textured with pea-size bits of lard. Add some icy water, use a fork to moisten the whole mixture, then use hands to smooth evenly by folding over gently, incorporating dry and wet components. Do not overwork, this will result in a tough dough. The faster you can do this the better.
Shape in a disc and cover with plastic wrap, let cool in the fridge about 40 minutes. In a medium pan at low heat, simmer cream and sugar till sugar is melted and evenly glossy, about 10 minutes. Cool on the stove.
Take the cold dough disc out of the fridge and cut in half. Roll out the half in a circle between 2 layers of wax paper on the table with a rolling pin, make sure it is the same thickness all around. Carefully peel the wax paper off the top, place a hand under and flip into the pie plate, peel other layers off slowly while making sure dough is laying flat against the 9-inch plate. Add flour to filling, whisk briskly and pour into dough in pie plate.
Roll out the second half in the same way as the first but in a smaller diameter. Peel the top wax paper off. Using a butter knife, cut long narrow strips about half an inch in width. Starting in the middle of the pie plate use the longest strips of dough and place on top of the filling, from top to bottom and from side to side, interweave and gently interlace more strips by gently lifting and placing back. When done all the way to the edges, fold the bottom dough over top layer of the top strips end, evening out thickness as you go around the edge of the pie plate. Crimp up edge of dough with three finger tips.
Place on the middle rack of the oven at a 375 degree Fahrenheit temperature. The pie will bake while the filling thickens, the dough becoming a dark golden brown. After 50 minutes, if filling is bubbling up in center, it should be ready. I find no need to place anything underneath plate while cooking.
