Pastries stay crisp when they are baked thoroughly, cooled properly, and stored in a dry environment. Minimizing exposure to humidity, high-moisture fillings, and condensation is key to preserving that perfect crunch.

To maintain crispness, avoid placing warm pastries in closed containers, as the resulting steam will soften the crust. Additionally, using a moisture barrier (such as a thin layer of chocolate or an egg wash) between the dough and a moist filling can help prevent the pastry from becoming soggy.
