Make the pie crust and roll out half of it for the bottom crust.
Bring a pot of water to boil and drop the peaches or nectarines in for a few minutes, then remove. This makes the peel just slide right off! Cut the nectarines into slices and mix with the flour, sugar and lemon juice. Pour the nectarines into the pie shell, then roll out the second half of the dough and cover, pinching the two crusts together.
Cut a few vent slits into the top crust and bake for 15 minutes at 450, then lower the heat to 350F and bake another 40-50 minutes.
