Select large apples that hold their shape when cooked. In season, I like Jonathan. By Thanksgiving, Idared is a good choice. Peel, quarter, core, and slide the apples. Leave the sliced quarters together as you go (they don’t brown as quickly if there’s less exposed surface, and they pack better. Fill the pie plate and then keep piling on apples until they are nearly as tall over the plate as the plate is deep.
Dump apples into a large bowl. Drizzle lemon juice over all, and then sprinkle on about half a cup of brown sugar (more if the apples aren’t sweet, or if you like a sweeter pie) about a tablespoon of corn starch, a heaping teaspoon of cinnamon, and maybe 3/4 teaspoon of nutmeg. Sometimes I mix the powers before adding them to the apple, but it’s not critical. Now stir everything around wit your hands, trying to separate every apple slice and get some sugar on each one. Move gently to avoid breaking the slices.
Allow the apple slices to sit for 15 minutes, so the sugar dissolves and pulls out some juice. mix again, coating every slice with the now-homogenous brown liquid. If there’s a lot of liquid puddling in the bottom, you will discard it, so you might want to add a little more spice (and sugar) if desired, and mix and wait and mix again.
Lay a crust into the pie plate. Layer about a third of the apples into the crust, trying to leave as little open space as possible. Then dot with butter. If you don’t eat butter, just leave this step out – there’s plenty of fat in the crust, the butter is only there for flavor. When I make pie for vegans, I routinely leave it out and it’s fine. Then layer another third of the apples, and dot with more butter. Then add the rest of the apple, leaving any excess liquid behind – that’s what will solidify into goo if you add too much of it to a pie. You can drink it if you like sweetened spiced apple juice. If you plan to make a lattice or other open crust, make sure the top layer of apples is symmetric and attractive.
Cover with a top crust, crimp the sides, cut some slits for steam, and bake.
