I am a novice baker and i would to try to make what we call in Rhode Island as Lemon Squares. They are basically a Lemon filling with a Top and Bottom flaky crust. I don't have a recipe or a technique on how to do this meaning adding the top crust. Most recipes i have found were just with a bottom crust?
I worked in RI many decades ago,
its regular pie dough, blind bake the base til half baked.
They roll and put the dough in a tray and use a second tray on top to press it down. use something to weight it down, like an old cup or plate.
The filling they use is from a bucket , you can use canned filling, it tastes the same.
pie dough for top, roll it up on a 1 inch dowel and unroll over the filling.
eggwash, score the pattern with a fork and bake 30 minutes at 350.
try doing it in small alum foil oblong trays, 4x7 inch, it makes it easier to handle the dough.
The pie dough is just crisco recipe on every can of crisco .
