The micro-perforated pastry rings are used for cooking pies in the oven for example and shortcrust pastry in general.

The micro-holes in fact allow to support the edges avoiding collapse with a white cooking. The cooking in white is the cooking of the shortcrust pastry without filling, which will then be put later in the cold and above all guarantee uniform cooking thanks to the evaporation of humidity.

Regular edges, well-defined corners, optimal welding; this is what the Calder company guarantees.
