Rub the butter into 260 g of the flour with 10 g of the sugar and the salt until the mixture looks like coarse crumbs, then stir in the ice water and press it into a dough.
Divide the dough into two discs, wrap them and chill for 30 minutes.
Heat the oven to 200C. Peel, core and thinly slice the apples and toss them with the lemon juice, 100 g of the sugar, the remaining flour, the cinnamon and the nutmeg.
Roll out one disc, line a 23 cm pie dish with it and fill it with the apples, mounding them in the center.
Roll out the second disc, lay it over the filling, trim and crimp the edges and cut a few slits in the top.
Brush the top with the milk, sprinkle with the remaining sugar and bake for 20 minutes, then lower the oven to 180C and bake for 35-40 minutes more, until the filling bubbles through the slits.
Leave the pie to cool until just warm so the filling sets before slicing.
