Score pastry sheet. Use a knife to lightly score the dough about 1 inch from the edge, drawing a rectangle shape into the dough (don’t go all the way through!).

Egg wash. In a small bowl whisk the eggs white and then use a basting brush to brush the egg white over the outer edges of the dough.

Bake. Move the parchment paper with the tart dough on it to a baking sheet and put it in the oven to bake for 12 minutes. When it has finished baking set aside.

Prep asparagus. While the pastry bakes wash and trim about 15 asparagus spears. Par-cook your asparagus by either boiling them for 1-2 minutes or steaming them.. Once they are done run them under cold water to stop the cooking process and then dry thoroughly with a paper towel.
