On the “729 layers” debate, the one thing that tightened my mille-feuille was swapping half the bench flour for rice flour — keeps the laminations crisp without toughening or gray streaks. It stays true to the classic, but if your kitchen’s really dry, brush off any excess before the last fold so it doesn’t dust the edges.

I freeze dough 8–10 minutes between turns; prevents smear — don’t overdo; https://www.seriouseats.com/puff-pastry…

For clean, even layers I bake the puff sheets “under weight”: perforated mat + parchment, dough, parchment, then a second sheet pan on top for the first 12–15 minutes at 400°F — , it’s the only thing that stops blowouts for me. I finish uncovered and dust with a little powdered sugar to caramelize; if you don’t have a perforated mat, parchment on both sides still works, @crispquest.

Six single turns gets me to the “729” sweet spot, but the real win is a long rest after the third — “stop when the dough says stop” — and if the butter tightens, I park it 10 minutes before rolling again; pushing through just marbles the layers… If your room runs warm, use shorter passes with more rests instead of colder dough, or you’ll get shatter instead of lift.
