A nostalgic and comforting mixed berry deep-dish pie with a flaky buttery crust and a sweet-tart berry filling, perfect for any occasion.
Keep butter and water ice cold for a flaky crust. Chill dough discs before rolling to prevent shrinking. Drain frozen berries well to avoid soggy crust. Use egg wash for golden crust and tent edges with foil if browning too fast. Cool pie for at least 2 hours before slicing.
