How to Revive Stale Pastry
Pastries lose their edge quickly as moisture migrates from the inside to the outside, turning the crust soft and the center dense. A short trip through a hot oven reverses this process, returning the flakiness to the layers.
Watch the color, not the clock
The goal is to warm the fats inside the dough without browning the outside further. If the edges begin to darken, pull them out immediately.

Introducing Controlled Moisture
A fine mist of water creates a localized steam environment in the oven, which prevents the pastry from drying out further while the heat restores the flake.
The method.
Preheat the oven
Set your oven to 350°F (175°C). Avoid higher temperatures, as they will burn the exterior before the center warms through.
Prepare the pastry
Place the pastries on a parchment-lined baking sheet, leaving enough space between them for air to circulate.
Mist lightly
Use a spray bottle to apply a very light coating of water. Do not soak the pastry; it should look matte, not glistening.
Heat through
Place in the center rack. After 5 minutes, test the firmness by tapping the crust. If it feels brittle and warm, remove it.
Cool briefly
Let the pastry sit on the tray for 60 seconds before eating. This allows the steam to stabilize, ensuring a crisp finish.
Other turns to take.
The Pan Method
For a single pastry, use a dry skillet over medium-low heat. Cover with a lid for the first minute to trap steam, then remove the lid to crisp the bottom.
When it doesn't go to plan.
Never use a microwave, as it will turn the pastry soft and rubbery by gelatinizing the starches.
If the pastry has a sugar glaze, keep the misting to a bare minimum to prevent the sugar from melting into a sticky puddle.
Frozen-then-stale pastries should be thawed at room temperature before following these steps.

Can I do this more than once?
No. Each cycle of heating and cooling degrades the quality of the fats and proteins. Revive only what you intend to eat immediately.
