Puff pastry bakes at high heat—400°F (200°C) or hotter. It needs that blast to create steam and lift off. Lower heat makes it weep butter.
Don’t peek. Opening the oven door lets out steam. That’s your rising power escaping. Sit on your hands. Wait the full time.
Let it cool completely. I know, I know. You want to dive in. But hot puff pastry is a gooey mess. It needs ten minutes to set. Use that time to brag about your creation.
