Making a pot pie with a puff pastry crust. Plan to bake it just before serving. Do I put the pastry on now, or just before baking?
I'd say put it on just before baking because you want it to stay chilled.An egg wash on a yolk mixed with cream is a nice touch. Yum.
And AFTER the egg wash, take a paring knife with a good sharp point, and very lightly carve a design (wavy lines, a vertical-horizontal grid, use your imagination!), just going through the first very top layers of the pastry. After it is baked, the results are beautiful!
