Make with frozen berries
Step One
Mix the berries with lemon zest, juice, flour (can be gluten free), and some cornstarch.
Step Two
Cook on the stove until a thick and juicy filling comes together.
Step Three
Place into a pie crust. See my site for how to make vegan and gluten free crusts! Or use one that is store-bought for a super easy shortcut! Bake for 1 hour.
