For the crust: Mix salt in flour and cut butter into flour with a fork or pastry cutter until well blended. Add enough water until the dough scrapes away from the bowl - usually about 3-5 Tbsp (amount as original recipe is written // adjust if altering batch size).
For the filling: Next prep the apples. Add them to the same bowl as you made the dough in and toss with sugar, cinnamon and flour. Add to pie crust and top with 1 Tbsp butter, scored into little dots or strips (amount as original recipe is written // adjust if altering batch size).
For the topping: In the same bowl, add the crumble topping ingredients and mix with fingers or a pastry cutter until crumbly. Then pour it over the pie, spreading it evenly to coat. Bake at 400 for 35-45 minutes, or until the pie is warm and bubbly and the top is golden brown. If you notice the crumble top getting too brown, simply top it with foil.
