blueberry mascarpone pie with ritz crackers?

I used a store bought crust due to my lack of kitchen space

for the cheese layer
1 8oz pkg mascarpone cheese
2 eggs
cornstarch
sugar
vanilla
a squeeze of lemon juice

for the berry layer
2 pints blueberries
sugar

cracker layer
ritz crackers
sugar

or
graham crackers

crust
2 deep dish pie crusts or make your own.

mix mascarpone, eggs, cornstarch (i eyeballed this), sugar, vanilla and lemon juice in a bowl, set aside

mix blueberries and sugar in another bowl.

spread cheese mixture atop pie crust. add  blueberries. crumble crackers atop, if using ritz sprinkle a bit of sugar. dot with butter. cover with other dough.

bake at 300 degrees for an hour then raise temperature and bake till crust is browned to your liking.
