The perforated finish makes your pastry adhere to the ring during baking, the adhesion keeping the pastry edge from collapsing. Your baked tarts have uniform edges and are cooked evenly throughout. No worries about sticking! As long as you crease the tart ring before you insert the dough, the ring disengages from the tart before the baking is over. Size: 45mm Quantity: 1 piece
