When baking puff pastry, what initial oven temperature helps maximize rise and why?

Rising in puff pastry comes from steam pushing apart the laminated layers. A hot start is essential to generate steam quickly and to set the layers around those expanding pockets before the butter melts too much, so the air gaps stay intact and the pastry can lift. The initial temperature around 210–220°C is hot enough to produce immediate steam and begin setting the crust, which helps trap that force and maximize rise. If the oven is cooler, steam forms more slowly and the fat can melt and leak between layers, reducing lift. Going much higher, like 260°C, would brown the exterior too fast and can hinder full internal expansion, while starting as low as 150°C won’t generate enough steam early to achieve a strong rise.
