-
Mash with love: Drain the vegetables and mash them together with butter, salt, pepper, and heavy cream until smooth and creamy. Keep this warm while you prepare the filling.

Customize Wisely: Feel free to experiment with seasonal veggies, but be mindful not to overload the filling; balance is key for flavor and texture.
