Good morning. I believe the reason the base of the pie dough sticks to the bottom of your glass pie plate is the dough is short of sufficient fat. Why don’t you first try spritzing some of that “PAM” junk into the pie plate & see if that will provide help. If not modify the recipe by adding more fat like crisco, butter, or cream cheese or even veg. oil into the pastry.
Mariel, as far as the reducing the acidity taste of the lemon concoction goes you can consider replacing the 1.5 oz of lemon juice with additional water…or if you do not mind just reducing the lemon & the level of the pie will be short in height by approx 1/8th of an inch.. Consider reducing a little of the cornstarch when doing this option. Or try adding additional sweetner either sugar or honey. That may work out for you.
Good luck to you Mariel I am sure you will succeed in whatever you decide to do. Enjoy the rest of the day.
