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?
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
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!
