That high heat blast with steam is key for oven spring. Drop to 450 after the initial 20, let it go another 25 or so. Makes the crust way better.

Oh man, you fell into the classic "just one more episode" trap with The Bear, didn't you? That show is a black hole for free time. Wilson.sam has a point about the real life kitchen disaster shows, but honestly, watching Gordon Ramsay yell at people for having a dirty fridge is just depressing after the artful chaos of The Bear. For that same "everything is falling apart but in a cool way" feeling, you need to watch the movie "Uncut Gems." It's just two hours of Adam Sandler making increasingly bad choices while everyone yells, and your heart tries to beat out of your chest. It's the same kind of stressful, can't-look-away energy.
