Mushroom Turnovers

A lovely soft dough which crisps up beautifully when baked. The filling is very good but I think is a little too heavy on butter and flour and a little too light on seasoning. The filling takes only a few minutes and can be made and let to cool to room temperature. The dough needs to chill till it firms up--but both can be made well ahead -- the dough needs to soften a bit after being chilled. The Filled turnovers can be chilled (or frozen) and baked from the fridge--just adjust the baking time.
